Hi Jesús,
Please send this query to the gcc-help list, instead of this one. This list
is about programming the internals of the gcc compiler itself; the gcc-help
list is for help using the compiler and programming /with/ it.
(Also, when you re-send your post, add some details about what computer and
operating system you're using. And you might want to google "O_NONBLOCK"
while you're waiting for a reply...)
cheers,
DaveK
