Arguments

Description

CheckIfFileIsExecutable is a procedure used to examine the specified file name to see if it is executable. CheckIfFileIsExecutable is implemented for UNIX-like environments, and allows a process to better determine if the file can be executed on the platform or OS, and to get better error messages when it cannot.

CheckIfFileIsExecutable raises an exception with a specific message when the platform or OS facilities indicate it is necessary.

Use FileIsExecutable to determine of a file is executable without raising an exception.
