Description

Macro: DEBUG_MEMORY

#define DEBUG_MEMORY

DEBUG_MEMORY replaces the allocator with a collect and debug shell to the libc allocator. DEBUG_MEMORY should only be activated when debugging libxml i.e. if libxml has been configured with --with-debug-mem too. #define DEBUG_MEMORY_FREED #define DEBUG_MEMORY_LOCATION

Function: xmlCleanupMemory

void	xmlCleanupMemory		(void)

Free up all the memory allocated by the library for its own use. This should not be called by user level code.

Function type: xmlFreeFunc

Function type: xmlFreeFunc
void	xmlFreeFunc			(void * mem)

Signature for a free() implementation.

Function: xmlGcMemGet

int	xmlGcMemGet			(xmlFreeFunc * freeFunc, 
					 xmlMallocFunc * mallocFunc, 
					 xmlMallocFunc * mallocAtomicFunc, 
					 xmlReallocFunc * reallocFunc, 
					 xmlStrdupFunc * strdupFunc)

Provides the memory access functions set currently in use The mallocAtomicFunc is specialized for atomic block allocations (i.e. of areas useful for garbage collected memory allocators

Function: xmlGcMemSetup

int	xmlGcMemSetup			(xmlFreeFunc freeFunc, 
					 xmlMallocFunc mallocFunc, 
					 xmlMallocFunc mallocAtomicFunc, 
					 xmlReallocFunc reallocFunc, 
					 xmlStrdupFunc strdupFunc)

Override the default memory access functions with a new set This has to be called before any other libxml routines ! The mallocAtomicFunc is specialized for atomic block allocations (i.e. of areas useful for garbage collected memory allocators Should this be blocked if there was already some allocations done ?

Function: xmlInitMemory

int	xmlInitMemory			(void)

Initialize the memory layer.

Function: xmlMallocAtomicLoc

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

a malloc() equivalent, with logging of the allocation info.

Function type: xmlMallocFunc

Function type: xmlMallocFunc
void *	xmlMallocFunc			(size_t size)

Signature for a malloc() implementation.

Function: xmlMallocLoc

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

a malloc() equivalent, with logging of the allocation info.

Function: xmlMemBlocks

int	xmlMemBlocks			(void)

Provides the number of memory areas currently allocated

Function: xmlMemDisplay

void	xmlMemDisplay			(FILE * fp)

show in-extenso the memory blocks allocated

Function: xmlMemFree

void	xmlMemFree			(void * ptr)

a free() equivalent, with error checking.

Function: xmlMemGet

int	xmlMemGet			(xmlFreeFunc * freeFunc, 
					 xmlMallocFunc * mallocFunc, 
					 xmlReallocFunc * reallocFunc, 
					 xmlStrdupFunc * strdupFunc)

Provides the memory access functions set currently in use

Function: xmlMemMalloc

void *	xmlMemMalloc			(size_t size)

a malloc() equivalent, with logging of the allocation info.

Function: xmlMemRealloc

void *	xmlMemRealloc			(void * ptr, 
					 size_t size)

a realloc() equivalent, with logging of the allocation info.

Function: xmlMemSetup

int	xmlMemSetup			(xmlFreeFunc freeFunc, 
					 xmlMallocFunc mallocFunc, 
					 xmlReallocFunc reallocFunc, 
					 xmlStrdupFunc strdupFunc)

Override the default memory access functions with a new set This has to be called before any other libxml routines ! Should this be blocked if there was already some allocations done ?

Function: xmlMemShow

void	xmlMemShow			(FILE * fp, 
					 int nr)

show a show display of the memory allocated, and dump the @nr last allocated areas which were not freed

Function: xmlMemStrdupLoc

char *	xmlMemStrdupLoc			(const char * str, 
					 const char * file, 
					 int line)

a strdup() equivalent, with logging of the allocation info.

Function: xmlMemUsed

int	xmlMemUsed			(void)

Provides the amount of memory currently allocated

Function: xmlMemoryDump

void	xmlMemoryDump			(void)

Dump in-extenso the memory blocks allocated to the file .memorylist

Function: xmlMemoryStrdup

char *	xmlMemoryStrdup			(const char * str)

a strdup() equivalent, with logging of the allocation info.

Function type: xmlReallocFunc

Function type: xmlReallocFunc
void *	xmlReallocFunc			(void * mem, 
					 size_t size)

Signature for a realloc() implementation.

Function: xmlReallocLoc

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

a realloc() equivalent, with logging of the allocation info.

Function type: xmlStrdupFunc

Function type: xmlStrdupFunc
char *	xmlStrdupFunc			(const char * str)

Signature for an strdup() implementation.
