+ +

The `fdblock` program

+ +

+fdblock sets or unsets the O_NONBLOCK flag on a given file descriptor +(which makes reading or writing non-blocking or blocking), then executes +a program. +

+ +

Interface

+ +

+     fdblock [ -n ] fd prog...
+

+ +

+fdblock makes the file descriptor number fd blocking, +no matter what its previous state was. It then execs into prog +with its arguments. +

+ +

Options

+ +

-n : non-blocking. Sets fd to non-blocking +mode instead of blocking mode. If used on stdin (0) or stdout (1), this +option will make a lot of command-line programs behave improperly, because +most simple command-line programs only support blocking stdin and stdout. +Make sure you know what you are doing.

+ +

Notes

+ +

fdblock has no portable shell equivalent.
