CURLINFO_CONTENT_TYPE(3) Library Functions Manual CURLINFO_CONTENT_TYPE(3)
NAME
CURLINFO_CONTENT_TYPE - 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 did not send a valid
Content-Type header or that the protocol used does not support this.
The ct pointer is set to 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.
The modern way to get this header from a response is to instead use the
curl_easy_header(3) function.
PROTOCOLS
This functionality affects http only
EXAMPLE
int main(void)
{
CURL *curl = curl_easy_init();
if(curl) {
CURLcode res;
curl_easy_setopt(curl, CURLOPT_URL, "https://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
