NAME
CURLOPT_VERBOSE - verbose mode
SYNOPSIS
#include <curl/curl.h> CURLcode curl_easy_setopt(CURL *handle, CURLOPT_VERBOSE, long onoff);
DESCRIPTION
Set the onoff parameter to 1 to make the library display a lot of verbose information about its operations on this handle. Useful for libcurl and/or protocol debugging and understanding. The verbose information is sent to stderr, or the stream set with CURLOPT_STDERR(3). You hardly ever want this enabled in production use, you almost always want this used when you debug/report problems. To also get all the protocol data sent and received, consider using the CURLOPT_DEBUGFUNCTION(3).
DEFAULT
0, meaning disabled.
PROTOCOLS
This functionality affects all supported protocols
EXAMPLE
int main(void) { CURL *curl = curl_easy_init(); if(curl) { curl_easy_setopt(curl, CURLOPT_URL, "https://example.com"); /* ask libcurl to show us the verbose output */ curl_easy_setopt(curl, CURLOPT_VERBOSE, 1L); /* Perform the request */ curl_easy_perform(curl); } }
AVAILABILITY
Added in curl 7.1
RETURN VALUE
Returns CURLE_OK
