Function Documentation

void* xcalloc_f	(	size_t	nmemb,
		size_t	size,
		const char *	file,
		int	line
	)

calloc

Parameters

nmemb	number of members
size	size of member
file	fname location of use
line	line location of use

Returns

buffer

This function is invoked via macro xcalloc in which file and line are set automatically.

Definition at line 297 of file xmalloc.c.

void xfree_f	(	void *	p,
		const char *	file,
		int	line
	)

free

Parameters

p	string to be freed (might be NULL)
file	fname location of use
line	line location of use

This function is invoked via macro xfree in which file and line are set automatically.

Definition at line 336 of file xmalloc.c.

References log_level, xfree_d, and yaz_log().

void* xmalloc_f	(	size_t	size,
		const char *	file,
		int	line
	)

malloc

Parameters

size	size of buffer to be allocated
file	fname location of use
line	line location of use

Returns

buffer

This function is invoked via macro xmalloc in which file and line are set automatically.

void xmalloc_trav_f	(	const char *	s,
		const char *	file,
		int	line
	)

logs all xmalloc buffers

Parameters

s	not used
file	fname location of use
line	line location of use

This function is invoked via macro xmalloc_trav in which file and line are set automatically. Only if TRACE_XMALLOC > 1 this function does any real work!

void* xrealloc_f	(	void *	o,
		size_t	size,
		const char *	file,
		int	line
	)

realloc

Parameters

o	buffer to be reallocated
size	size of buffer to be allocated
file	fname location of use
line	line location of use

Returns

buffer

This function is invoked via macro xrealloc in which file and line are set automatically.

char* xstrdup_f	(	const char *	p,
		const char *	file,
		int	line
	)

strdup

Parameters

p	string to be cloned
file	fname location of use
line	line location of use

Returns

resulting string

This function is invoked via macro xstrdup in which file and line are set automatically.

	)

strndup

Parameters

p	string to be cloned
n	max size of resulting string (excluding 0)
file	fname location of use
line	line location of use

Returns

resulting string

This function is invoked via macro xstrndup in which file and line are set automatically.
