@comment POSIX.1: Not supported
@deftypevr Macro int ENOTSUP
@comment errno 118 @c DO NOT REMOVE
Not supported. A function returns this error when certain parameter
values are valid, but the functionality they request is not available.
This can mean that the function does not implement a particular command
or option value or flag bit at all. For functions that operate on some
object given in a parameter, such as a file descriptor or a port, it
might instead mean that only @emph{that specific object} (file
descriptor, port, etc.) is unable to support the other parameters given;
different file descriptors might support different ranges of parameter
values.
If the entire function is not available at all in the implementation,
it returns @code{ENOSYS} instead.
