Function Documentation

yaz_fclose()

int yaz_fclose

(

FILE *

f

)

closes file

Parameters

f	FILE handle

Return values

-1	on failure
0	on success

Definition at line 38 of file tpath.c.

yaz_filepath_comp()

size_t yaz_filepath_comp	(	const char **	path_p,
		const char **	comp
	)

get next path component in filepath

Parameters

path_p	pointer to path (updated to "next" entry if any)
comp	upon pointer to component (if component is found)

Return values

0	no component found (and no more componennts)
>0	length of component (length of *comp)

A filepath has components separted by colon. For example /usr/lib/modules:c:/my:/:lib which has these components "/usr/lib/modules", "c:/my", "/", "lib"

yaz_filepath_resolve()

char * yaz_filepath_resolve	(	const char *	fname,
		const char *	path,
		const char *	base,
		char *	fullpath
	)

resolve file on path

Parameters

fname	"short" filename (without path)
path	the path (dir1:dir2,..) - ala Unix
base	can be added to relative paths (NULL for no append)
fullpath	the full path to filename (if successful)

Returns

fullpath or NULL if file could not be found

Be sure to allocate at least 1024 bytes for fullpath
