- .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 ");"
- .ad
- .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)) {
- return (size_t) -1;
- }
- return total_size;
- }
