It does?  What error?  I see no error, just a return value meaning
there's no such file.

The magic, if there is one, depends on the application, because only
the application knows the semantics of the file-name argument for the
program to be invoked.  So I don't see how a general-purpose utility
function could solve the problem.  Unless I misunderstand the problem
you have.
