@ -36,12 +36,13 @@ 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
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.
The prototypes for the given callbacks should match these:
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);"
