curldown is this new file format for libcurl man pages. It is markdown inspired with differences: - Each file has a set of leading headers with meta-data - Supports a small subset of markdown - Uses .md file extensions for editors/IDE/GitHub to treat them nicely - Generates man pages very similar to the previous ones - Generates man pages that still convert nicely to HTML on the website - Detects and highlights mentions of curl symbols automatically (when their man page section is specified) tools: - cd2nroff: converts from curldown to nroff man page - nroff2cd: convert an (old) nroff man page to curldown - cdall: convert many nroff pages to curldown versions - cd2cd: verifies and updates a curldown to latest curldown This setup generates .3 versions of all the curldown versions at build time. CI: Since the documentation is now technically markdown in the eyes of many things, the CI runs many more tests and checks on this documentation, including proselint, link checkers and tests that make sure we capitalize the first letter after a period... Closes #12730

# NAME
|
|
|
|
CURLOPT_STDERR - redirect stderr to another stream
|
|
|
|
# SYNOPSIS
|
|
|
|
~~~c
|
|
#include <curl/curl.h>
|
|
|
|
CURLcode curl_easy_setopt(CURL *handle, CURLOPT_STDERR, FILE *stream);
|
|
~~~
|
|
|
|
# DESCRIPTION
|
|
|
|
Pass a FILE * as parameter. Tell libcurl to use this *stream* instead of
|
|
stderr when showing the progress meter and displaying CURLOPT_VERBOSE(3)
|
|
data.
|
|
|
|
If you are using libcurl as a Windows DLL, this option causes an exception and
|
|
a crash in the library since it cannot access a FILE * passed on from the
|
|
application. A work-around is to instead use CURLOPT_DEBUGFUNCTION(3).
