- .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), "
