.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!
