       io_block - switch to blocking I/O

SYNTAX

       #include <io.h>

       void io_block(int64 fd);

DESCRIPTION

       io_block puts UNIX descriptor fd into ``blocking mode.''

       File  descriptors  are  normally  in  blocking  mode, except if they come from accept() or
       io_accept() and the listening socket was in non-blocking mode.
