static int	slogprintf (FILE stream, int newline, const char str, size_t n)
	va_list version of logprintf and backend.

	va_list version of logprintf and backend.
static void	log_copy (int enable)
	Sets up or terminates copying of standard streams into memory.

	Appends a message to a stream's in-memory buffer.

static void	log_purge (void)
	Deletes copied output without printing the contents.
int	logprintf (FILE stream, int newline, const char fmt,...)
	Like fprintf, but automatically teed to log files (and line-terminated if `newline` is true).
void	log_redirect (void)
	Sets up redirection of stdout and stderr to files. PhysicsFS must be initialized for this to work.
void	log_init (void)
	Sets up the logging subsystem. (Calling this ensures logging output is preserved until we have a place to save it. That happens after we set up PhysicsFS and call log_redirect().)
void	log_clean (void)
	Deletes useless (empty) log files from the current session.
int	log_warn (const char file, size_t line, const char func, const char *fmt,...)
	Prints warnings, but skips if they are repeated too much.

Function Documentation

◆ log_append()

void log_append	(	const FILE *	stream,
		const char *	str )

static

Appends a message to a stream's in-memory buffer.

Parameters

stream	Destination stream (stdout or stderr)
str	String to append.

Definition at line 263 of file log.c.

◆ log_clean()

void log_clean ( void )

Deletes useless (empty) log files from the current session.

Definition at line 228 of file log.c.

◆ log_cleanStream()

void log_cleanStream	(	PHYSFS_File **	file,
		const char *	fname,
		const char *	filedouble )

static

See also: log_clean

Definition at line 237 of file log.c.

◆ log_copy()

void log_copy ( int enable )

static

Sets up or terminates copying of standard streams into memory.

While copying is active, all stdout and stderr-bound messages that pass through logprintf will also be put into a buffer in memory, to be flushed when copying is disabled.

Parameters

enable Whether to enable or disable copying. Disabling flushes logs.

Definition at line 179 of file log.c.

◆ log_init()

void log_init ( void )

Sets up the logging subsystem. (Calling this ensures logging output is preserved until we have a place to save it. That happens after we set up PhysicsFS and call log_redirect().)

See also: log_copy

Definition at line 164 of file log.c.

◆ log_purge()

void log_purge ( void )

static

Deletes copied output without printing the contents.

Definition at line 211 of file log.c.

◆ log_redirect()

void log_redirect ( void )

Sets up redirection of stdout and stderr to files. PhysicsFS must be initialized for this to work.

Definition at line 130 of file log.c.

◆ log_warn()

int log_warn	(	const char *	file,
		size_t	line,
		const char *	func,
		const char *	fmt,
			... )

Prints warnings, but skips if they are repeated too much.

Definition at line 299 of file log.c.

◆ logprintf()

int logprintf	(	FILE *	stream,
		int	newline,
		const char *	fmt,
			... )

Like fprintf, but automatically teed to log files (and line-terminated if newline is true).

Definition at line 116 of file log.c.

◆ slogprintf()

int slogprintf	(	FILE *	stream,
		int	newline,
		const char *	str,
		size_t	n )

static

va_list version of logprintf and backend.

Definition at line 59 of file log.c.

◆ vlogprintf()

int vlogprintf	(	FILE *	stream,
		int	newline,
		const char *	fmt,
		va_list	ap )

static

va_list version of logprintf and backend.

Definition at line 87 of file log.c.
