NAME

mkfifo − make FIFO special file

SYNOPSIS

mkfifo path ...

DESCRIPTION

The mkfifo utility creates the FIFO special files named by its argument list.  The arguments are taken sequentially in the order specified, and each FIFO special file is either created completely or, in the case of an error or signal, not created at all. 

The mkfifo utility performs actions equivalent to: for each path argument, the mkfifo function is called with the argument path set to path and mode set to 0666. 

The mkfifo utility will terminate without action if it is passed a single invalid argument.  In the case of an argument list containing more than one path, it may continue processing all the members in that list and then display an error message at completion if one or more invalid arguments have been encountered.

Exit Status

The mkfifo utility exits with one of the following values:

0 All FIFO special files were created normally. 

>0
The utility was aborted due to errors in creating one or more FIFO special files.
