.TH curl_global_init_mem 3 "April 05, 2022" "libcurl 7.83.1" "libcurl Manual"
|
|
|
|
.SH NAME
|
|
curl_global_init_mem - Global libcurl initialization with memory callbacks
|
|
.SH SYNOPSIS
|
|
.nf
|
|
#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);
|
|
.fi
|
|
.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.
|
|
|
|
If you are using libcurl from multiple threads or libcurl was built with the
|
|
threaded resolver option then the callback functions must be thread safe. The
|
|
threaded resolver is a common build option to enable (and in some cases the
|
|
default) so we strongly urge you to make your callback functions thread safe.
|
|
|
|
All callback arguments must be set to valid function pointers. The
|
|
prototypes for the given callbacks must 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()
|
|
.PP
|
|
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!
|
|
.SH EXAMPLE
|
|
.nf
|
|
curl_global_init_mem(CURL_GLOBAL_DEFAULT, curl_malloc_cb,
|
|
curl_free_cb, curl_realloc_cb,
|
|
curl_strdup_cb, curl_calloc_cb);
|
|
.fi
|
|
.SH AVAILABILITY
|
|
Added in 7.12.0
|
|
.SH RETURN VALUE
|
|
CURLE_OK (0) means everything was ok, non-zero means an error occurred as
|
|
\fI<curl/curl.h>\fP defines - see \fIlibcurl-errors(3)\fP.
