This +function can only be called once, and it must be called \fBbefore\fP +curl_global_init(). + +The backend can be identified by the id (e.g. CURLSSLBACKEND_OPENSSL). The +backend can also be specified via the name parameter (passing -1 as id). +If both id and name are specified, the name will be ignored. If neither id +nor name are specified, the function will fail with +CURLSSLSET_UNKNOWN_BACKEND and set the "avail" pointer to the +NULL-terminated list of available backends. + +Upon success, the function returns CURLSSLSET_OK. + +If the specified SSL backend is not available, the function returns +CURLSSLSET_UNKNOWN_BACKEND and sets the "avail" pointer to a NULL-terminated +list of available SSL backends. + +The SSL backend can be set only once. If it has already been set, a +subsequent attempt to change it will result in a CURLSSLSET_TOO_LATE. + +\fBThis function is not thread safe.\fP You must not call it when any other +thread in the program (i.e. a thread sharing the same memory) is running. +This doesn't just mean no other thread that is using libcurl. + +.SH AVAILABILITY +This function was added in libcurl 7.56.0. Before this version, there was no +support for choosing SSL backends at runtime. +.SH RETURN VALUE +If this function returns CURLSSLSET_OK, the backend was successfully selected. + +If the chosen backend is unknown (or support for the chosed backend has not +been compiled into libcurl), the function returns CURLSSLSET_UNKNOWN_BACKEND. + +If the backend had been configured previously, or if curl_global_init() has +already been called, the function returns CURLSSLSET_TOO_LATE. +.SH "SEE ALSO" +.BR curl_global_init "(3), " +.BR libcurl "(3) " diff --git a/docs/libcurl/libcurl.3 b/docs/libcurl/libcurl.3 index 6618734b4..e8ecc31da 100644 --- a/docs/libcurl/libcurl.3 +++ b/docs/libcurl/libcurl.3 @@ -38,6 +38,10 @@ while using libcurl.
