| .TH curl_easy_perform 3 "5 Mar 2001" "libcurl 7.7" "libcurl Manual" |
| .SH NAME |
| curl_easy_perform - Perform a file transfer |
| .SH SYNOPSIS |
| .B #include <curl/curl.h> |
| .sp |
| .BI "CURLcode curl_easy_perform(CURL *" handle ");" |
| .ad |
| .SH DESCRIPTION |
| This function is called after the init and all the \fIcurl_easy_setopt(3)\fP |
| calls are made, and will perform the transfer as described in the options. It |
| must be called with the same |
| .I handle |
| as input as the curl_easy_init call returned. |
| |
| You can do any amount of calls to \fIcurl_easy_perform(3)\fP while using the |
| same handle. 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 |
| \fIcurl_easy_setopt(3)\fP 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. |
| .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), " |
