◆ xmlFreeFunc typedef void(* xmlFreeFunc) (void *mem)
Signature for a free() implementation.
-
Parameters
-
mem an already allocated block of memory
◆ xmlMallocFunc typedef void *(* xmlMallocFunc) (size_t size)
Signature for a malloc() implementation.
-
Parameters
-
size the size requested in bytes
-
Returns
-
a pointer to the newly allocated block or NULL in case of error.
◆ xmlReallocFunc typedef void *(* xmlReallocFunc) (void *mem, size_t size)
Signature for a realloc() implementation.
-
Parameters
-
mem an already allocated block of memory size the new size requested in bytes
-
Returns
-
a pointer to the newly reallocated block or NULL in case of error.
◆ xmlStrdupFunc typedef char *(* xmlStrdupFunc) (const char *str)
Signature for an strdup() implementation.
-
Parameters
-
str a zero terminated string
-
Returns
-
the copy of the string or NULL in case of error.
◆ xmlCleanupMemory() void xmlCleanupMemory ( void )
-
Deprecated
-
This function is a no-op. Call xmlCleanupParser to free global state but see the warnings there. xmlCleanupParser should be only called once at program exit. In most cases, you don't have call cleanup functions at all.
◆ xmlGcMemGet()
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
-
Deprecated
-
Use xmlMemGet.
-
Parameters
-
freeFunc place to save the free() function in use mallocFunc place to save the malloc() function in use mallocAtomicFunc place to save the atomic malloc() function in use reallocFunc place to save the realloc() function in use strdupFunc place to save the strdup() function in use
-
Returns
-
0 on success
◆ xmlGcMemSetup()
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

-
Use xmlMemSetup.
Should this be blocked if there was already some allocations done ?
-
Parameters
-
freeFunc the free() function to use mallocFunc the malloc() function to use mallocAtomicFunc the malloc() function to use for atomic allocations reallocFunc the realloc() function to use strdupFunc the strdup() function to use
