Description

Details

>DEBUG_MEMORY

#define DEBUG_MEMORY

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


>MEM_LIST

#define MEM_LIST /* keep a list of all the allocated memory blocks */

keep track of all allocated blocks for error reporting


>xmlFreeFunc ()

void        (*xmlFreeFunc)                  (void*);

Param1 : 


>xmlMallocFunc ()

void*       (*xmlMallocFunc)                (size_t);

Param1 : 


>xmlReallocFunc ()

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

Param1 : 
Param2 : 


>xmlStrdupFunc ()

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

Param1 : 
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 : 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 currently 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


>xmlMalloc()

#define     xmlMalloc(size)

Wrapper for the malloc() function used in the XML library

size : number of bytes to allocate


>xmlRealloc()

#define     xmlRealloc(ptr, size)

Wrapper for the realloc() function used in the XML library

ptr : pointer to the existing allocated area
size : number of bytes to allocate


>xmlMemStrdup()

#define     xmlMemStrdup(str)

Wrapper for the strdup() function, xmlStrdup() is usually preferred

str : pointer to the existing string


>xmlMallocLoc ()

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

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
