curleasyperform(3) libcurl Manual curleasyperform(3)
NAME
curleasyperform - Perform a file transfer
SYNOPSIS
##include <>
CURLcode curleasyperform(CURL **handle);;
DESCRIPTION
This function is called after the init and all the curleasysetopt(3)
calls are made, and will perform the transfer as described in the
options. It must be called with the same handle as input as the
curleasyinit call returned.
You can do any amount of calls to curleasyperform(3) 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 con-
nection 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 curleasysetopt(3) between the invokes to set options
for the following curleasyperform.
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.
RETURN VALUE
0 means everything was ok, non-zero means an error occurred as
defines. If the CURLOPTERORBUFER was set with
curleasysetopt there will be a readable error message in the error
buffer when non-zero is returned.
