Remove the PROTOCOLS section from the source files completely and instead generate them based on the header data in the curldown files. It also generates TLS backend information for options marked for TLS as protocol. Closes #13175

# NAME
|
|
|
|
CURLOPT_VERBOSE - verbose mode
|
|
|
|
# SYNOPSIS
|
|
|
|
~~~c
|
|
#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.
|
|
|
|
# EXAMPLE
|
|
|
|
~~~c
|
|
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);
|
|
}
|
|
}
