CURLINFO_CONTENT_TYPE man page
CURLINFO_CONTENT_TYPE ā get Content-Type
Synopsis
#include <curl/curl.h>
CURLcode curl_easy_getinfo(CURL *handle, CURLINFO_CONTENT_TYPE, char **ct);
Description
Pass a pointer to a char pointer to receive the content-type of the downloaded object. This is the value read from the Content-Type: field. If you get NULL, it means that the server didn't send a valid Content-Type header or that the protocol used doesn't support this.
The ct pointer will be NULL or pointing to private memory you MUST NOT free it - it gets freed when you call curl_easy_cleanup(3) on the corresponding CURL handle.
Protocols
HTTP(S)
Example
CURL *curl = curl_easy_init(); if(curl) { curl_easy_setopt(curl, CURLOPT_URL, "http://example.com"); res = curl_easy_perform(curl); if(!res) { /* extract the content-type */ char *ct = NULL; res = curl_easy_getinfo(curl, CURLINFO_CONTENT_TYPE, &ct); if(!res && ct) { printf("Content-Type: %s\n", ct); } } curl_easy_cleanup(curl); }
Availability
