curl_easy_strerror - return string describing error code

Added in curl 7.12.0

The curl_easy_strerror(3) function returns a string describing the CURLcode error code passed in the argument errornum. Typically applications also appreciate CURLOPT_ERRORBUFFER(3) for more specific error descriptions generated at runtime.

int main(void) { CURL *curl = curl_easy_init(); if(curl) { CURLcode res; /* set options */ /* Perform the entire transfer */ res = curl_easy_perform(curl); /* Check for errors */ if(res != CURLE_OK) fprintf(stderr, "curl_easy_perform() failed: %s\n", curl_easy_strerror(res)); } }
