# xs_errno(3) Manual Page

## NAME

xs_errno - retrieve value of errno for the calling thread

## SYNOPSIS

int xs_errno (void);

## DESCRIPTION

The xs_errno() function shall retrieve the value of the errno variable for the calling thread.

The xs_errno() function is provided to assist users on non-POSIX systems who are experiencing issues with retrieving the correct value of errno directly. Specifically, users on Win32 systems whose application is using a different C run-time library from the C run-time library in use by Crossroads will need to use xs_errno() for correct operation.

Important | Users not experiencing issues with retrieving the correct value of errno should not use this function and should instead access the errno variable directly.

## RETURN VALUE

The xs_errno() function shall return the value of the errno variable for the calling thread.

## ERRORS

No errors are defined.
