Subject: add isastream (obsolete STREAMS junk)
X-Git-Url: http://nsz.repo.hu/git/?p=musl;a=commitdiff_plain;h=106e75f7121b009c069733dcb8a70fe5e4380ab0;hp=106e75f7121b009c069733dcb8a70fe5e4380ab0

add isastream (obsolete STREAMS junk)

apparently some packages see stropts.h and want to be able to use
this. the implementation checks that the file descriptor is valid by
using fcntl/F_GETFD so it can report an error if not (as specified).
