Function Documentation

void explain_buffer_open_flags	(	struct explain_string_buffer_t *	sb,
		int	flags
	)

The explain_buffer_open_flags function may be used to decode the flags argument to the open(2) system call into a humnan readable string, which is one representation of how it would be written by a coder.

Parameters:

sb	where to put the constructed text. This makes it thread safe, given a suitabley safe buffer.
flags	the flags argument passed to the open(2) system call, second argument

Definition at line 158 of file open_flags.c.

int explain_parse_open_flags_or_die	(	const char *	text,
		const char *	caption
	)

The explain_pare_open_flags_or_die function may be used to parse a strings containing a symbolic representation of open() flags, turning it into a open flags value.

Parameters:

text	The text to be parsed to extract an open flags value.
caption	additional text to add to start of error message

Returns:

open flags value

Note:

If there is a parse error, a fatal error message is printed, and exit(EXIT_FAILURE) is called. If there is an error, this function will not return.
