The keyword specifies how option works when specified multiple times: - single: the last provided value replaces the earlier ones - append: it supports being provided multiple times - boolean: on/off values - mutex: flag-like option that disable anoter flag The 'gen.pl' script then outputs the proper and unified language for each option's multi-use behavior in the generated man page. The multi: header is requires in each .d file and will cause build error if missing or set to an unknown value. Closes #9759

In curl 7.86.0 and later, curl never uses NPN.
|
|
|
|
Disable the NPN TLS extension. NPN is enabled by default if libcurl was built
|
|
with an SSL library that supports NPN. NPN is used by a libcurl that supports
|
|
HTTP/2 to negotiate HTTP/2 support with the server during https sessions.
