.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.
This man page only adds documentation for the callbacks, see the
\fIcurl_global_init(3)\fP 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:
.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()
.SH "CAUTION"
Manipulating these gives considerable powers to the application to severely
screw things up for libcurl. Take care!
