.desc begin
The &func macro is the size of an array of char big enough to hold a string 
naming any file that the implementation expects to open;
If there is no practical file name length limit, &func is the recommended
size of such an array.  As file name string contents must meet other
system-specific constraints, some strings of length &func may not work.
.np
&func typically sizes an array to hold a file name.

.return begin
The &func macro returns a positive integer value.
