CURLINFO_PRIMARY_PORT(3) Library Functions Manual CURLINFO_PRIMARY_PORT(3) NAME CURLINFO_PRIMARY_PORT - get the latest destination port number SYNOPSIS #include <curl/curl.h> CURLcode curl_easy_getinfo(CURL *handle, CURLINFO_PRIMARY_PORT, long *portp); DESCRIPTION Pass a pointer to a long to receive the destination port of the most recent connection done with this curl handle. This is the destination port of the actual TCP or UDP connection libcurl used. If a proxy was used for the most recent transfer, this is the port number of the proxy, if no proxy was used it is the port number of the most recently accessed URL. PROTOCOLS This functionality affects all supported protocols 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 == CURLE_OK) { long port; res = curl_easy_getinfo(curl, CURLINFO_PRIMARY_PORT, &port); if(!res) printf("Connected to remote port: %ld\n", port); } curl_easy_cleanup(curl); } } AVAILABILITY Added in curl 7.21.0 RETURN VALUE curl_easy_getinfo(3) returns a CURLcode indicating success or error.
