Function Documentation

void explain_buffer_errno_fstatvfs	(	explain_string_buffer_t *	sb,
		int	errnum,
		int	fildes,
		struct statvfs *	data
	)

The explain_buffer_errno_fstatvfs function is used to obtain an explanation of an error returned by the fstatvfs(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.
fildes	The original fildes, exactly as passed to the fstatvfs(2) system call.
data	The original data, exactly as passed to the fstatvfs(2) system call.

void explain_buffer_errno_fstatvfs_explanation	(	explain_string_buffer_t *	sb,
		int	errnum,
		const char *	syscall_name,
		int	fildes,
		struct statvfs *	data
	)

The explain_buffer_errno_fstatvfs_explanation function is used to obtain the explanation (the part after "because") of an error returned by the fstatvfs(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.
fildes	The original fildes, exactly as passed to the fstatvfs(2) system call.
data	The original data, exactly as passed to the fstatvfs(2) system call.
