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 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 +\fICURLOPT_COPYPOSTFIELDS(3)\fP, unless another \fICURLOPT_POSTFIELDS(3)\fP or +\fICURLOPT_COPYPOSTFIELDS(3)\fP option is issued. +.SH DEFAULT +NULL +.SH PROTOCOLS +HTTP(S) +.SH EXAMPLE +.nf +CURL *curl = curl_easy_init(); +if(curl) { + char local_buffer[1024]="data to send"; + curl_easy_setopt(curl, CURLOPT_URL, "http://example.com"); + + /* size of the data to copy from the buffer and send in the request */ + curl_easy_setopt(curl, CURLOPT_POSTFIELDSIZE, 12L); + + /* send data from the local stack */ + curl_easy_setopt(curl, CURLOPT_COPYPOSTFIELDS, local_buffer); + + curl_easy_perform(curl); +} +.fi +.SH AVAILABILITY +Added in 7.17.1 +.SH RETURN VALUE +Returns CURLE_OK if the option is supported, CURLE_UNKNOWN_OPTION if not, or +CURLE_OUT_OF_MEMORY if there was insufficient heap space. +.SH "SEE ALSO" +.BR CURLOPT_POSTFIELDS "(3), " CURLOPT_POSTFIELDSIZE "(3), " |
