Function Documentation

hlhdf_alloc_calloc()

void * hlhdf_alloc_calloc	(	const char *	filename,
		int	lineno,
		size_t	npts,
		size_t	sz )

Same as calloc but debugged.

Parameters

[in]	filename	the name of the file the allocation occurs in
[in]	lineno	the linenumber
[in]	npts	number of points
[in]	sz	the number of bytes to be allocated

hlhdf_alloc_dump_heap()

void hlhdf_alloc_dump_heap

(

void

)

Dumps all blocks that not has been released.

hlhdf_alloc_free()

void hlhdf_alloc_free	(	const char *	filename,
		int	lineno,
		void *	ptr )

Releases the memory.

Parameters

[in]	filename	the name of the file the allocation occurs in
[in]	lineno	the linenumber
[in]	ptr	the pointer that should be freed

hlhdf_alloc_malloc()

void * hlhdf_alloc_malloc	(	const char *	filename,
		int	lineno,
		size_t	sz )

Allocates memory and keeps track on if it is released, overwritten and similar.

Parameters

[in]	filename	the name of the file the allocation occurs in
[in]	lineno	the linenumber
[in]	sz	the number of bytes to be allocated

hlhdf_alloc_print_statistics()

void hlhdf_alloc_print_statistics

(

void

hlhdf_alloc_realloc()

void * hlhdf_alloc_realloc	(	const char *	filename,
		int	lineno,
		void *	ptr,
		size_t	sz )

Same as realloc but debugged.

Parameters

[in]	filename	the name of the file the allocation occurs in
[in]	lineno	the linenumber
[in]	ptr	the original pointer
[in]	sz	the number of bytes to be allocated

hlhdf_alloc_strdup()

char * hlhdf_alloc_strdup	(	const char *	filename,
		int	lineno,
		const char *	str )
