! 25: .SH NAME
! 26: CURLOPT_POSTFIELDSIZE \- size of POST data pointed to
! 27: .SH SYNOPSIS
! 28: #include <curl/curl.h>
! 29:
! 30: CURLcode curl_easy_setopt(CURL *handle, CURLOPT_POSTFIELDSIZE, long size);
! 31: .SH DESCRIPTION
! 32: If you want to post data to the server without having libcurl do a strlen() to
! 33: measure the data size, this option must be used. When this option is used you
! 34: can post fully binary data, which otherwise is likely to fail. If this size is
! 35: set to -1, the library will use strlen() to get the size.
! 36:
! 37: If you post more than 2GB, use \fICURLOPT_POSTFIELDSIZE_LARGE(3)\fP.
! 38: .SH DEFAULT
! 39: -1
! 40: .SH PROTOCOLS
