- .\" generated by cd2nroff 0.1 from CURLOPT_VERBOSE.md
- .TH CURLOPT_VERBOSE 3 "2025-01-17" libcurl
- .SH NAME
- CURLOPT_VERBOSE \- verbose mode
- .SH SYNOPSIS
- .nf
- #include <curl/curl.h>
- CURLcode curl_easy_setopt(CURL *handle, CURLOPT_VERBOSE, long onoff);
- .fi
- .SH DESCRIPTION
- Set the \fIonoff\fP parameter to 1 to make the library display a lot of
- verbose information about its operations on this \fIhandle\fP. Useful for
- libcurl and/or protocol debugging and understanding. The verbose information
- is sent to stderr, or the stream set with \fICURLOPT_STDERR(3)\fP.
- 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
- \fICURLOPT_DEBUGFUNCTION(3)\fP.
- .SH DEFAULT
- 0, meaning disabled.
- .SH PROTOCOLS
- This functionality affects all supported protocols
- .SH EXAMPLE
- .nf
- 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);
- }
- }
- .fi
- .SH AVAILABILITY
- Added in curl 7.1
