.TH curl_global_init_mem 3 "10 May 2004" "libcurl 7.12.0" "libcurl Manual"
.SH NAME
curl_global_init_mem - Global libcurl initialisation with memory callbacks
.SH SYNOPSIS
.B #include <curl/curl.h>
.nf
.B "CURLcode curl_global_init_mem(long " flags,
.B " curl_malloc_callback "m,
.B " curl_free_callback "f,
.B " curl_realloc_callback "r,
.B " curl_strdup_callback "s,
.B " curl_calloc_callback "c ");"
.SH DESCRIPTION
This function works exactly as \fIcurl_global_init(3)\fP 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. \fBIf you are using libcurl from multiple threads or with
the threaded resolver (the default in Windows) the callback replacement
functions must be thread safe.\fP
The prototypes for the given callbacks should match these:
.IP "void *malloc_callback(size_t size);"
To replace malloc()
.IP "void free_callback(void *ptr);"
To replace free()
.IP "void *realloc_callback(void *ptr, size_t size);"
To replace realloc()
.IP "char *strdup_callback(const char *str);"
To replace strdup()
.IP "void *calloc_callback(size_t nmemb, size_t size);"
To replace calloc()
.RE
This function is otherwise the same as \fIcurl_global_init(3)\fP, please refer
to that man page for documentation.
.SH "CAUTION"
Manipulating these gives considerable powers to the application to severely
screw things up for libcurl. Take care!
