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.

When you use this function, all callback arguments must be set to valid function pointers. If you are using libcurl from multiple threads or with the threaded resolver (the default in Windows) the callback replacement functions must be thread safe.

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()
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!
