curl_global_init_mem(3)

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.

This man page only adds documentation for the callbacks, see the curl_global_init(3) man page for all the rest. When you use this function, all callback arguments must be set to valid function pointers.

The prototypes for the given callbacks should 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()

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