debug()

void debug	(	int	flag,
		const char *	fmt,
			...
	)

Output a debugging message.

The message will be printed to the previously specified output if the specified flag is present in the current debugging mask.

debug_has_flag()

bool debug_has_flag

(

int

flag

)

Check if a debugging flag is currently set on the debugging mask.

Here is the caller graph for this function:

debug_parse_mask()

int debug_parse_mask

(

const char *

str

)

Parse the debugging mask.

The mask is parsed from the specified string and sets the global debugging mask. If there is any error while parsing a negative number is returned.

Here is the caller graph for this function:

debug_set_mask()

void debug_set_mask

(

mask

)

Set the debugging mask.

The mask determines what debugging flags are going to take effect at run-time. The output will be set to stderr if it has not been set before.
