If you +intend to transfer more than one file, you are even encouraged to do +so. libcurl will then attempt to re-use the same connection for the following +transfers, thus making the operations faster, less CPU intense and using less +network resources. Just note that you will have to use +.I curl_easy_setopt +between the invokes to set options for the following curl_easy_perform. + +You must never call this function simultaneously from two places using the +same handle. Let the function return first before invoking it another time. If +you want parallel transfers, you must use several curl handles. + +Before libcurl version 7.7: You are only allowed to call this function once +using the same handle. If you want to do repeated calls, you must call +curl_easy_cleanup and curl_easy_init again first. +.SH RETURN VALUE +0 means everything was ok, non-zero means an error occurred as +.I <curl/curl.h> +defines. If the CURLOPT_ERRORBUFFER was set with +.I curl_easy_setopt +there will be a readable error message in the error buffer when non-zero is +returned. +.SH "SEE ALSO" +.BR curl_easy_init "(3), " curl_easy_setopt "(3), " +.SH BUGS +Surely there are some, you tell me! |
