Integrating Perl and C

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

Hi
I have a C program which reads temperatures from a circuit I have built. An example function is as follows -

float Get_Temperature();
[download]

If I wanted to use this function in a Perl program how would I go about it? Also, if I had the following C function -

BOOL isThisHot(int);
[download]

how would I go about using it in a Perl program, thanks for your help.
Alan

See perldoc perlxs. Or perhaps Inline::C. Update: Yep, I should definitely have mentioned perldoc perlxstut. -- <http://dave.org.uk> "The first rule of Perl club is you do not talk about Perl club." -- Chip Salzenberg	[reply]

perlxstut is probably a better starting point, but you'll make your way to the other eventually. But yeah, Inline::C might be the better option. There's also always SWIG, too (if you were interested in using other languages as well).	[reply]

If you are using a Windows machine and your function is in a DLL, you could also use Win32::API: `use Win32::API (); my $Get_Temperature = Win32::API->new( 'mydll', 'float Get_Temperature()', ); my $isThisHot = Win32::API->new( 'mydll', 'BOOL isThisHot(int)', ); my $temp = $Get_Temperature->Call(); my $hot = $isThisHot->Call($temp);` [download] or `use Win32::API (); Win32::API->Import('mydll', 'float Get_Temperature()'); Win32::API->Import('mydll', 'BOOL isThisHot(int)'); my $temp = Get_Temperature(); my $hot = isThisHot($temp);` [download]	[reply] [d/l] [select]
