CURLOPT_PASSWORD - password to use in authentication

Added in curl 7.19.1

blank

Pass a char pointer as parameter, which should be pointing to the null-terminated password to use for the transfer. The CURLOPT_PASSWORD(3) option should be used in conjunction with the CURLOPT_USERNAME(3) option. 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.

int main(void) { CURL *curl = curl_easy_init(); if(curl) { CURLcode res; curl_easy_setopt(curl, CURLOPT_URL, "https://example.com/foo.bin"); curl_easy_setopt(curl, CURLOPT_PASSWORD, "qwerty"); res = curl_easy_perform(curl); curl_easy_cleanup(curl); } }
