curl_global_init_mem(3)		libcurl	Manual	       curl_global_init_mem(3)

NAME
       curl_global_init_mem  - Global libcurl initialisation with memory call-
       backs

SYNOPSIS
       #include	<curl/curl.h>
       CURLcode	curl_global_init_mem(long  flags,
	curl_malloc_callback  m,
	curl_free_callback  f,
	curl_realloc_callback  r,
	curl_strdup_callback  s,
	curl_calloc_callback  c	);

DESCRIPTION
       This function works exactly as curl_global_init(3) with	one  addition:
       it  allows  the	application  to	set callbacks to replace the otherwise
       used internal memory functions.

       If you are using	libcurl	from multiple threads  or  libcurl  was	 built
       with  the  threaded resolver option then	the callback functions must be
       thread safe. The	threaded resolver is a common build option  to	enable
       (and  in	 some  cases the default) so we	strongly urge you to make your
       callback	functions thread safe.

       All callback arguments must be set to valid function pointers. The pro-
       totypes for the given callbacks must match these:

       void *malloc_callback(size_t size);
	      To replace malloc()

       void free_callback(void *ptr);
	      To replace free()

       void *realloc_callback(void *ptr, size_t	size);
	      To replace realloc()

       char *strdup_callback(const char	*str);
	      To replace strdup()

       void *calloc_callback(size_t nmemb, size_t size);
	      To replace calloc()
       This  function is otherwise the same as curl_global_init(3), please re-
       fer to that man page for	documentation.

CAUTION
       Manipulating these gives	considerable powers to the application to  se-
       verely screw things up for libcurl. Take	care!
