Functions
static void	log_copy (int enable)
	Sets up or terminates copying of standard streams into memory.
static void	log_append (FILE *stream, char *str)
	Appends a message to a stream's in-memory buffer.
static void	log_cleanStream (PHYSFS_File **file, const char *fname, const char *filedouble)
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.

Function Documentation

log_append()

static void log_append ( FILE * stream, 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 239 of file log.c.

log_clean()

void log_clean

(

void

)

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

Definition at line 205 of file log.c.

log_cleanStream()

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

static

log_clean

Definition at line 214 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 156 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().)

log_purge()

static void log_purge ( void )

static

Deletes copied output without printing the contents.

Definition at line 188 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 108 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).
