       curl_global_init_mem - Global libcurl initialization with memory


       #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);


       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.


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


        curl_global_init_mem(CURL_GLOBAL_DEFAULT, curl_malloc_cb,
                             curl_free_cb, curl_realloc_cb,
                             curl_strdup_cb, curl_calloc_cb);


       Added in 7.12.0


       CURLE_OK (0) means everything was OK, non-zero means an error occurred as
       <curl/curl.h> defines - see libcurl-errors(3).
