The code reads: if the number of arguments is not equal to 1
I have no idea whether it will return true of false

curlopt_verbose
CURLOPT_VERBOSE(3) curl_easy_setopt options CURLOPT_VERBOSE(3)
NAME
CURLOPT_VERBOSE - set verbose mode on/off
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. Very useful for
libcurl and/or protocol debugging and understanding. The verbose information will be sent to stderr, or the stream set with CUR-
LOPT_STDERR(3).
You hardly ever want this set in production use, you will almost always want this 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
All
EXAMPLE
CURL *curl = curl_easy_init();
if(curl) {
curl_easy_setopt(curl, CURLOPT_URL, "http://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
Always
RETURN VALUE
Returns CURLE_OK
SEE ALSO
CURLOPT_STDERR(3), CURLOPT_DEBUGFUNCTION(3),
