Function Documentation

char* explain_tempnam_on_error	(	const char *	dir,
		const char *	prefix
	)

The explain_tempnam_on_error function is used to call the tempnam(3) system call. On failure an explanation will be printed to stderr, obtained from the explain_tempnam(3) function.

Parameters:

dir	The dir, exactly as to be passed to the tempnam(3) system call.
prefix	The prefix, exactly as to be passed to the tempnam(3) system call.

Returns:

The value returned by the wrapped tempnam(3) system call.

Example:

This function is intended to be used in a fashion similar to the following example:

 char *result = explain_tempnam_on_error(dir, prefix);
 if (!result)
 {
     ...cope with error
     ...no need to print error message
 }
