curl_global_init_mem man page

## 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 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 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!
