You have to set a write function that will be called when curl receives
the data. You can do whatever you want with the raw info retrieved by
the funciton
........
curl_easy_setopt(handle, CURLOPT_WRITEFUNCTION, write_data);
..........
size_t write_data(void *buffer, size_t size, size_t nmemb, void *userp)
{
char *data;
fprintf(stderr, "Allocating %ld * %ld = %ld\n", (long)size,
(long)nmemb, (long)(size * nmemb));
data = calloc(size, nmemb);
if(!data)
return -1;
fprintf(stderr, "Allocation succeeded\n");
memcpy(data, buffer, size * nmemb);
return size * nmemb;
}

Dear Friends,
I am using CURL to get HTTP response.
The default output for CURL is stdout, but i am unable to change it to
a variable.
Right now,
I am using a temporary file for this purpose and read it to process it.
Is there any way, by which method i will get CURL output to a string
or any structure?
===================== main.c =====================
#include <stdio.h>
#include <stdlib.h>
#include <curl/curl.h>
int
main()
{
CURL *curl;
char *data1[512];
FILE *fp;
fp = fopen("/tmp/curl","w");
curl = curl_easy_init();
if(curl) {
curl_easy_setopt(curl, CURLOPT_URL, "http://127.0.0.1";);
curl_easy_setopt(curl, CURLOPT_HEADER, 0);
curl_easy_setopt(curl, CURLOPT_WRITEDATA, fp);
curl_easy_perform(curl);
curl_easy_cleanup(curl);
}
fclose(fp);
return 0;
}
================================================
Thanks and Regards
Jai
