Function Documentation

isc_result_t isc_stdio_open	(	const char *	filename,
		const char *	mode,
		FILE **	fp
	)

These functions are wrappers around the corresponding stdio functions.

They return a detailed error code in the form of an an isc_result_t. ANSI C does not guarantee that stdio functions set errno, hence these functions must use platform dependent methods (e.g., the POSIX errno) to construct the error code.
