errno

Runs on:

QNX Neutrino

Options:

error_number

The error number to be explained.

Description:

The errno utility displays the string equivalent for the error_numbers supplied on the command line. The output is written to the standard output.

This utility is useful in cases where a program has indicated that a numerical error occurred and hasn't provided the ASCII string equivalent of that errno value. Users who don't have access to the C header file <errno.h> don't have the option of using:

grep error_number /usr/include/errno.h

The errno utility is more convenient and is available to all users.

Examples:

Find the string equivalent of error number 2:

$ errno 2
errno 2: No such file or directory
$

Exit status:

0

Always returns 0.
