Function Documentation

void explain_buffer_errno_setregid	(	explain_string_buffer_t *	sb,
		int	errnum,
		gid_t	rgid,
		gid_t	egid
	)

The explain_buffer_errno_setregid function is used to obtain an explanation of an error returned by the setregid(2) system call. The least the message will contain is the value of strerror(errnum), but usually it will do much better, and indicate the underlying cause in more detail.

Parameters:

sb	The string buffer to print the message into. If a suitable buffer is specified, this function is thread safe.
errnum	The error value to be decoded, usually obtained from the errno global variable just before this function is called. This is necessary if you need to call any code between the system call to be explained and this function, because many libc functions will alter the value of errno.
rgid	The original rgid, exactly as passed to the setregid(2) system call.
egid	The original egid, exactly as passed to the setregid(2) system call.

void explain_buffer_errno_setregid_explanation	(	explain_string_buffer_t *	sb,
		int	errnum,
		const char *	syscall_name,
		gid_t	rgid,
		gid_t	egid
	)

The explain_buffer_errno_setregid_explanation function is used to obtain the explanation (the part after "because") of an error returned by the setregid(2) system call (and similar).

Parameters:

sb	The string buffer to print the message into. If a suitable buffer is specified, this function is thread safe.
errnum	The error value to be decoded, usually obtained from the errno global variable just before this function is called. This is necessary if you need to call any code between the system call to be explained and this function, because many libc functions will alter the value of errno.
syscall_name	The name of the offending system call.
rgid	The original rgid, exactly as passed to the setregid(2) system call.
egid	The original egid, exactly as passed to the setregid(2) system call.
