NAME
       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.
