NAME

       curl_global_init_mem - Global libcurl initialisation with memory callbacks

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 prototypes 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 refer to that man page for documentation.

CAUTION

       Manipulating these gives considerable powers to the application to severely screw things up for libcurl. Take care!
