.\" generated by cd2nroff 0.1 from CURLINFO_CONTENT_TYPE.md .TH CURLINFO_CONTENT_TYPE 3 "2026-09-02" libcurl .SH NAME CURLINFO_CONTENT_TYPE \- Content\-Type of response .SH SYNOPSIS .nf #include CURLcode curl_easy_getinfo(CURL *handle, CURLINFO_CONTENT_TYPE, char **ct); .fi .SH 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 \fBct\fP pointer is NULL or points to private memory. You \fBmust not\fP free it. It gets freed automatically when you call \fIcurl_easy_cleanup(3)\fP on the corresponding curl handle. The modern way to get this header from a response is to instead use the \fIcurl_easy_header(3)\fP function. .SH PROTOCOLS This functionality affects http only .SH EXAMPLE .nf int main(void) { CURL *curl = curl_easy_init(); if(curl) { CURLcode result; curl_easy_setopt(curl, CURLOPT_URL, "https://example.com"); result = curl_easy_perform(curl); if(result == CURLE_OK) { /* extract the content-type */ char *ct = NULL; result = curl_easy_getinfo(curl, CURLINFO_CONTENT_TYPE, &ct); if(!result && ct) { printf("Content-Type: %s\\n", ct); } } curl_easy_cleanup(curl); } } .fi .SH AVAILABILITY Added in curl 7.9.4 .SH RETURN VALUE \fIcurl_easy_getinfo(3)\fP returns a CURLcode indicating success or error. CURLE_OK (0) means everything was OK, non\-zero means an error occurred, see \fIlibcurl\-errors(3)\fP. .SH SEE ALSO .BR CURLOPT_HEADERFUNCTION (3), .BR curl_easy_getinfo (3), .BR curl_easy_header (3), .BR curl_easy_setopt (3)
