Detailed Description

A target that will write log messages to a provided I/O stream.

Events logged to a StreamTarget will be separated by a newline. Stream targets are equivalent to file targets, except that the associated stream must be opened and closed by the caller rather than the target itself. Stream targets also provide a quick way to log to stderr and stdout, which is not possible with a FileTarget.

Constructor & Destructor Documentation

◆ StreamTarget() [1/2]

stumpless::StreamTarget::StreamTarget ( struct stumpless_target * equivalent )

◆ StreamTarget() [2/2]

stumpless::StreamTarget::StreamTarget	(	const char *	name,
		FILE *	stream )

Opens a stream target for the given stream.

Parameters

name	The name of this target.
stream	The stream to log events to.

◆ ~StreamTarget()

stumpless::StreamTarget::~StreamTarget ( void )

Closes the target and releases all memory owned by it.

Does NOT close the stream associated with the target.

Member Function Documentation

◆ GetDefaultAppName()

const char * stumpless::StreamTarget::GetDefaultAppName ( void )

Returns the default app name used by this target.

The returned character buffer must be freed by the caller when it is no longer needed to avoid memory leaks. Available since release v2.0.0.

Returns: The default app name of this target.

◆ GetDefaultFacility()

Facility stumpless::StreamTarget::GetDefaultFacility ( void )

Gets the default facility of this target.

Returns: The default facility of this target.

◆ GetDefaultMsgid()

const char * stumpless::StreamTarget::GetDefaultMsgid ( void )

Returns the default msgid used by this target.

The returned character buffer must be freed by the caller when it is no longer needed to avoid memory leaks. Available since release v2.0.0.

Returns: The default msgid of this target.

◆ GetFilter()

stumpless_filter_func_t stumpless::StreamTarget::GetFilter ( void )

Returns the current filter used by this target to determine if entries should be allowed through it.

Note that NULL is a valid return value from this function, indicating that the target does not currently have a filter set. Available since release v2.1.0.

Returns: The filter function in use by this target.

◆ GetMask()

int stumpless::StreamTarget::GetMask ( void )

Gets the log mask of this target.

The mask is a bit field of severities that this target will allow if the default mask-based filter is in use. These can be formed and checked using the STUMPLESS_SEVERITY_MASK and STUMPLESS_SEVERITY_MASK_UPTO macros, and combining them using bitwise or operations. Available since release v2.1.0.

Returns: The current mask of this target.

◆ GetName()

const char * stumpless::StreamTarget::GetName ( void )

Returns the name of this target.

The returned character buffer must be freed by the caller when it is no longer needed to avoid memory leaks. Available since release v2.0.0.

Returns: The name of this Target.

◆ GetOption()

int stumpless::StreamTarget::GetOption ( int option )

Gets the given option for this target.

While the returned value is the option if it is set, callers can also simply use the truth value of the return to see if the provided option is set.

Parameters

option The option to check this target for.

Returns: The option if it is set on the target. If the option is not set, then zero is returned.

◆ IsOpen()

bool stumpless::StreamTarget::IsOpen ( void )

Checks to see if this target is open.

Returns: True if the target is open, false otherwise.

◆ Log() [1/4]

StreamTarget & stumpless::StreamTarget::Log	(	const char *	message,
			... )

Writes a string message to this target.

Parameters

message	The message to log, optionally containing any format specifiers valid in printf. This may be NULL, in which case an event with no message is logged.
...	Substitutions for any format specifiers provided in message. The number of substitutions provided must exactly match the number of specifiers given.

Returns: The modified target.

◆ Log() [2/4]

StreamTarget & stumpless::StreamTarget::Log ( Entry entry )

Writes an Entry to this target.

Parameters

entry the entry to write

Returns: The modified target.

◆ Log() [3/4]

StreamTarget & stumpless::StreamTarget::Log	(	Facility	facility,
		Severity	severity,
		const char *	message,
			... )

Writes a log message with the given facility and severity to this target.

Parameters

facility	The facility code of the message.
severity	The severity code of the message.
message	The message to log, optionally containing any format specifiers valid in printf.
...	Substitutions for any format specifiers provided in message. The number of substitutions provided must exactly match the number of specifiers given.

Returns: The modified target.

◆ Log() [4/4]

StreamTarget & stumpless::StreamTarget::Log	(	int	priority,
		const char *	message,
			... )

Writes a log message with the given priority to this target.

Parameters

priority	The priority of the message, described in RFC 5424 as the PRIVAL. This should be the bitwise or of the integer values of a Facility and a Severity.
message	The message to log, optionally containing any format specifiers valid in printf.
...	Substitutions for any format specifiers provided in message. The number of substitutions provided must exactly match the number of specifiers given.

Returns: The modified target.

◆ Open()

void stumpless::StreamTarget::Open ( void )

Opens this target if it has been paused.

◆ OpenStderr()

static StreamTarget stumpless::StreamTarget::OpenStderr ( const char * name )

static

Opens a stream target to stderr.

This is equivalent to creating a new target with stderr provided as the stream.

Parameters

name	The name of the newly created target.

Returns: The newly created target.

◆ OpenStdout()

static StreamTarget stumpless::StreamTarget::OpenStdout ( const char * name )

static

Opens a stream target to stdout.

This is equivalent to creating a new target with stdout provided as the stream.

Parameters

name	The name of the newly created target.

Returns: The newly created target.

◆ SetDefaultAppName()

StreamTarget & stumpless::StreamTarget::SetDefaultAppName ( const char * app_name )

Sets the default app name for this target.

Parameters

app_name The new default app name, as a NULL-terminated string.

Returns: The modified target.

◆ SetDefaultFacility()

StreamTarget & stumpless::StreamTarget::SetDefaultFacility ( int facility )

Sets the default facility of the target.

Parameters

facility The default facility for the target to use. This should be a STUMPLESS_FACILITY value.

Returns: The modified target.

◆ SetDefaultMsgid()

StreamTarget & stumpless::StreamTarget::SetDefaultMsgid ( const char * msgid )

Sets the default message id for this target.

Parameters

msgid The new default message id, as a NULL-terminated string.

Returns: The modified target.

◆ SetFilter()

StreamTarget & stumpless::StreamTarget::SetFilter ( stumpless_filter_func_t filter )

Sets the filter used by this target to determine whether entries should be logged to it.

Available since release v2.1.0.

Parameters

filter The new filter to use for this target.

Returns: The modified target.

◆ SetMask()

StreamTarget & stumpless::StreamTarget::SetMask ( int mask )

Sets the log mask of a target.

The mask is a bit field of severities that this target will allow if the default mask-based filter is in use. These can be formed and checked using the STUMPLESS_SEVERITY_MASK and STUMPLESS_SEVERITY_MASK_UPTO macros, and combining them using bitwise or operations. Available since release v2.1.0.

Parameters

mask	The new mask to use for this target.

Returns: The modified target.

◆ SetOption()

StreamTarget & stumpless::StreamTarget::SetOption ( int option )

Sets an option on a target.

Parameters

option The option to set. This should be a STUMPLESS_OPTION value.

Returns: The modified target.

◆ UnsetOption()

StreamTarget & stumpless::StreamTarget::UnsetOption ( int option )

Unsets an option on a target.

Parameters

option The option to unset. This should be a STUMPLESS_OPTION value.

Returns: The modified target.
