CURLOPT_NETRC_FILE(3) Library Functions Manual CURLOPT_NETRC_FILE(3) NAME CURLOPT_NETRC_FILE - filename to read .netrc info from SYNOPSIS #include CURLcode curl_easy_setopt(CURL *handle, CURLOPT_NETRC_FILE, char *file); DESCRIPTION Pass a char pointer as parameter, pointing to a null-terminated string containing the full path name to the file you want libcurl to use as .netrc file. If this option is omitted, and CURLOPT_NETRC(3) is set, libcurl checks for a .netrc file in the current user's home directory. The application does not have to keep the string around after setting this option. Using this option multiple times makes the last set string override the previous ones. Set it to NULL to disable its use again. DEFAULT NULL PROTOCOLS This functionality affects all supported protocols EXAMPLE int main(void) { CURL *curl = curl_easy_init(); if(curl) { CURLcode ret; curl_easy_setopt(curl, CURLOPT_URL, "ftp://example.com/"); curl_easy_setopt(curl, CURLOPT_NETRC, CURL_NETRC_OPTIONAL); curl_easy_setopt(curl, CURLOPT_NETRC_FILE, "/tmp/magic-netrc"); ret = curl_easy_perform(curl); } } AVAILABILITY Added in curl 7.11.0 RETURN VALUE curl_easy_setopt(3) returns a CURLcode indicating success or error. CURLE_OK (0) means everything was OK, non-zero means an error occurred, see libcurl-errors(3).
