who : symbol? path : path-string? perms : (listof (or/c 'read 'write 'execute 'delete 'exists))
Checks whether (current-security-guard) permits access to the file specified by path with the permissions perms. See make-security-guard for more information on perms.
The symbol who should be the name of the function on whose behalf the security check is performed; it is passed to the security guard to use in access-denied errors.
Like _file and _path, but conversion from Racket to C first completes the path using path->complete-path then cleanses it using cleanse-path, then checks that the current security guard grants access on the resulting complete path with perms. As an output value, identical to _path.
