.TH curl_formget 3 "20 June 2006" "libcurl 7.15.5" "libcurl Manual"
|
||
|
|
.SH NAME
|
||
|
|
curl_formget - serialize a previously built multipart/formdata HTTP POST chain
|
||
|
|
.SH SYNOPSIS
|
||
|
|
.nf
|
||
|
|
.B #include <curl/curl.h>
|
||
|
|
|
||
|
|
int curl_formget(struct curl_httppost * form, void *userp,
|
||
|
|
curl_formget_callback append );
|
||
|
|
.SH DESCRIPTION
|
||
|
|
curl_formget() is used to serialize data previously built/appended with
|
||
|
|
\fIcurl_formadd(3)\fP. Accepts a void pointer as second argument named
|
||
|
|
\fIuserp\fP which will be passed as the first argument to the
|
||
|
|
curl_formget_callback function.
|
||
|
|
|
||
|
|
.BI "typedef size_t (*curl_formget_callback)(void *" userp, " const char *" buf,
|
||
|
|
.BI " size_t " len ");"
|
||
|
|
|
||
|
|
The curl_formget_callback will be executed for each part of the HTTP POST
|
||
|
|
chain. The character buffer passed to the callback must not be freed. The
|
||
|
|
callback should return the buffer length passed to it on success.
|
||
|
|
|
||
|
|
If the \fBCURLFORM_STREAM\fP option is used in the formpost, it will prevent
|
||
|
|
\fIcurl_formget(3)\fP from working until you've performed the actual HTTP
|
||
|
|
request as only then will libcurl get the actual read callback to use!
|
||
|
|
.SH RETURN VALUE
|
||
|
|
0 means everything was ok, non-zero means an error occurred
|
||
|
|
.SH EXAMPLE
|
||
|
|
.nf
|
||
|
|
|
||
|
|
size_t print_httppost_callback(void *arg, const char *buf, size_t len)
|
||
|
|
{
|
||
|
|
fwrite(buf, len, 1, stdout);
|
||
|
|
(*(size_t *) arg) += len;
|
||
|
|
return len;
|
||
|
|
}
|

|
|

|
|
size_t print_httppost(struct curl_httppost *post)
|
||

|
size_t total_size = 0;
|
||
|
|
if(curl_formget(post, &total_size, print_httppost_callback)) {
|
||
|
|
return (size_t) -1;
|
