Checkpath

checkpath is a function that allows you to verify if a file path is in the white list of the engine and can therefore be accessed.

Syntax

checkpath(FILE_PATH,ACCESS_MODE)

FILE_PATH is the path of a file or a directory which accessibility must be checked. The files do not need to exist, the only check that is done is the control against the white list. For example, if C:\tmp\subdir\myfile.src is checked and if C:\tmp is in the white list, the return is positive even if the subdir folder does not exist.
ACCESS_MODE can have the value 0 (if you want to check the read access) or 1 (if you want to check the write access).

This function returns a 1 if the requested access rights are not denied by the white list definition; otherwise it returns a 0.
