NAME¶
CURLOPT_COPYPOSTFIELDS - have libcurl copy data to POST
SYNOPSIS¶
#include <curl/curl.h>
CURLcode curl_easy_setopt(CURL *handle, CURLOPT_COPYPOSTFIELDS, char *data);
DESCRIPTION¶
Pass a char * as parameter, which should be the full data to post in a HTTP POST
operation. It behaves as the
CURLOPT_POSTFIELDS(3) option, but the
original data is instead copied by the library, allowing the application to
overwrite the original data after setting this option.
Because data are copied, care must be taken when using this option in
conjunction with
CURLOPT_POSTFIELDSIZE(3) or
CURLOPT_POSTFIELDSIZE_LARGE(3): If the size has not been set prior to
CURLOPT_COPYPOSTFIELDS(3), the data is assumed to be a zero terminated
string; else the stored size informs the library about the byte count to copy.
In any case, the size must not be changed after
CURLOPT_COPYPOSTFIELDS(3), unless another
CURLOPT_POSTFIELDS(3)
or
CURLOPT_COPYPOSTFIELDS(3) option is issued.

NULL
