- .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 severly
- screw things up for libcurl. Take care!
