.SH NAME
|
|
curl_formget - serialize a previously built multipart/formdata HTTP POST chain
|
|
.SH SYNOPSIS
|
|
.B #include <curl/curl.h>
|
|
.sp
|
|
.BI "void curl_formget(struct curl_httppost *" form, " void *" arg,
|
|
.BI " 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 which will be
|
|
passed to the curl_formget_callback function.
|
|
|
|
.BI "typedef size_t (*curl_formget_callback)(void *" arg, " const char *" buf,
|
|
.BI " size_t " len ");"
|
|
.nf
|
|
|
|
The curl_formget_callback will be executed for each part of the HTTP POST
|
|
chain. The void *arg pointer will be the one passed as second argument to
|
|
curl_formget(). The character buffer passed to it must not be freed. The
|
|
callback should return the buffer length passed to it on success.
|
|
.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)) {
|
|
