problems using 'fdecls' in C::Scan

mtr4cv has asked for the wisdom of the Perl Monks concerning the following question:

I'm attempting to use C::Scan (version 0.74 in ActiveState 631 on Windows NT) to get a list of the functions ('fdecls') in a C file. I'm getting the error:

"The name specified is not recognized as an internal or external command, operable program or batch file."

Via the debugger, I found that the error message occurs at line 862 of C/Scan.pm in C::Preprocessed::text. The line is:
my $oh = select $stream;

Does anyone have any idea what the problem is? Can anyone explain to me what the above line is doing? I tried 'defines_no_args' in C::Scan and it worked fine.
Thanks for any help!

The line is: `my $oh = select $stream;` [download] Can anyone explain to me what the above line is doing? That's saving the file handle (a.k.a. input or output stream, hence the variable name) refered to by `$stream` in the variable `$oh`. One wishes that the original developer had used more descriptive variable names, but it's difficult to be harsh based on just one line of code. --t. alex "Here's the chocolates, and here's the flowers.
