Try:
PREDEFINED = char_varying()=char_varying
If want the length to be captured, you would need a custom filter to
preprocess your VOS C sources.
In Perl, something like the following should work:
#!perl -w
use strict;
use warnings;
while (<>)
{
s/char_varying\s*[(]\s*(\d+)\s*[)]\s+([_A-Za-z][_A-Za-z0-9]*)\s*[;]/char_varying
$2[$1];/;
print $_;
}
Note that the above will expect an actual, decimal (or octal) number
between the parenthesis after char_varying.
For it to accept a number or symbol, try replacing:
(\d+)
with:
([_A-Za-z0-9]+)
This alternate expression will also match hexadecimal numbers.
