	Allocates memory and keeps track on if it is released, overwritten and similar.
void *	rave_alloc_calloc (const char *filename, int lineno, size_t npts, size_t sz)
	Same as calloc but debugged.
void *	rave_alloc_realloc (const char *filename, int lineno, void *ptr, size_t sz)
	Same as realloc but debugged.
char *	rave_alloc_strdup (const char *filename, int lineno, const char *str)
	Same as strdup but debugged.
void	rave_alloc_free (const char *filename, int lineno, void *ptr)
	Releases the memory.
void	rave_alloc_dump_heap (void)
	Dumps all blocks that not has been released.
void	rave_alloc_print_statistics (void)
	Prints the statistics for the heap.

Typedef Documentation

RaveHeap_t

typedef struct RaveHeap_t RaveHeap_t

A linked list where each entry corresponds to one allocation.

RaveHeapEntry_t

typedef struct RaveHeapEntry_t RaveHeapEntry_t

Keeps track on one allocation.

Function Documentation

rave_alloc_calloc()

void * rave_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

rave_alloc_dump_heap()

void rave_alloc_dump_heap

(

void

)

Dumps all blocks that not has been released.

rave_alloc_free()

void rave_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

rave_alloc_malloc()

void * rave_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

rave_alloc_print_statistics()

void rave_alloc_print_statistics

(

void

)

Prints the statistics for the heap.

rave_alloc_realloc()

void * rave_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

rave_alloc_strdup()

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

Same as strdup but debugged.

Parameters

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