`Param1` :
Returns :

xmlFree

extern xmlFreeFunc xmlFree;

xmlMalloc

extern xmlMallocFunc xmlMalloc;

xmlRealloc

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 ?

`freeFunc` :	the free() function to use
`mallocFunc` :	the malloc() function to use
`reallocFunc` :	the realloc() function to use
`strdupFunc` :	the strdup() function to use
Returns :	0 on success

xmlMemGet ()

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

Return the memory access functions set currently in use

`freeFunc` :	the free() function in use
`mallocFunc` :	the malloc() function in use
`reallocFunc` :	the realloc() function in use
`strdupFunc` :	the strdup() function in use
Returns :	0 on success

xmlInitMemory ()

int         xmlInitMemory                   (void);

Initialize the memory layer.

Returns :

0 on success

xmlMemUsed ()

int         xmlMemUsed                      (void);

returns the amount of memory currenly allocated

Returns :

an int representing the amount of memory allocated.

xmlMemDisplay ()

void        xmlMemDisplay                   (FILE *fp);

show in-extenso the memory blocks allocated

fp : a FILE descriptor used as the output file, if NULL, the result is written to the file .memorylist

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

`fp` :	a FILE descriptor used as the output file
`nr` :	number of entries to dump

xmlMemoryDump ()

void        xmlMemoryDump                   (void);

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

xmlMallocLoc ()

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

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

`size` :	an int specifying the size in byte to allocate.
`file` :	the file name or NULL
`line` :	the line number

xmlReallocLoc ()

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

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

`ptr` :	the initial memory block pointer
`size` :	an int specifying the size in byte to allocate.
`file` :	the file name or NULL
`line` :	the line number

xmlMemStrdupLoc ()

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

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

`str` :
`file` :	the file name or NULL
`line` :	the line number
Returns :	a pointer to the new string or NULL if allocation error occured.
