Description

Details

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.

xmlFreeFunc ()

void        (*xmlFreeFunc)                  (void *mem);

Signature for a free() implementation.

mem : 

xmlMallocFunc ()

void*       (*xmlMallocFunc)                (size_t size);

Signature for a malloc() implementation.

size : 

xmlReallocFunc ()

void*       (*xmlReallocFunc)               (void *mem,
                                             size_t size);

Signature for a realloc() implementation.

mem : 
size : 

xmlStrdupFunc ()

char*       (*xmlStrdupFunc)                (const char *str);

Signature for an strdup() implementation.

str : 
Returns : 

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 : 
mallocFunc : 
reallocFunc : 
strdupFunc : 
Returns : 

xmlMemGet ()

                                             xmlMallocFunc *mallocFunc,
                                             xmlReallocFunc *reallocFunc,
                                             xmlStrdupFunc *strdupFunc);
