.TH CURLOPT_COPYPOSTFIELDS 3 "September 16, 2020" "libcurl 7.73.0" "curl_easy_setopt options"
|
|
|
|
.SH NAME
|
|
CURLOPT_COPYPOSTFIELDS \- have libcurl copy data to POST
|
|
.SH SYNOPSIS
|
|
#include <curl/curl.h>
|
|
|
|
CURLcode curl_easy_setopt(CURL *handle, CURLOPT_COPYPOSTFIELDS, char *data);
|
|
.SH DESCRIPTION
|
|
Pass a char * as parameter, which should be the full \fIdata\fP to post in a
|
|
HTTP POST operation. It behaves as the \fICURLOPT_POSTFIELDS(3)\fP 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 \fICURLOPT_POSTFIELDSIZE(3)\fP or
|
|
\fICURLOPT_POSTFIELDSIZE_LARGE(3)\fP: If the size has not been set prior to
|
|
\fICURLOPT_COPYPOSTFIELDS(3)\fP, the data is assumed to be a null-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
|
|
\fICURLOPT_COPYPOSTFIELDS(3)\fP, unless another \fICURLOPT_POSTFIELDS(3)\fP or
|
|
\fICURLOPT_COPYPOSTFIELDS(3)\fP option is issued.
