11.10. How do I call perl from C?
You need to see a recent copy of the
perlembed(1) pod page. By
"recent" it needs to be up to date with at least perl5.002.
Borrowing from Jon Orwant's preamble to that document:
Do you want to:
- Use C from Perl?
-
Read (at least)
the
perlcall(1),
the
perlapi(1),
the
perlxs(1),
the
perlxstut(1),
and the
perlguts(1) manpages.
- Use C++ from Perl?
- Recent changes to MakeMaker will make this easier. Be sure you are familiar
with
the
perlcall(1),
the
perlapi(1),
the
perlxs(1),
the
perlxstut(1),
and the
perlguts(1) manpages.
- Use an executable program from Perl?
-
Read about backquotes ``, system(), and
exec() built in perl functions. Try reading
the
perlfunc(1) manpage.
- Use Perl from Perl?
-
Read about do, eval, use and require.
The
perlfunc(1) manpage discusses these. For complete scripts you
may also make use of the backquotes ``, system(), or
exec() built in perl functions, but you may take a performance hit
in doing so (see
perlfunc(1) for information).
- Use C from C?
- Rethink your design.
- Use C++ from C++?
- See previous.
- Use Perl from C?
-
Read (at least)
the perlembed(1)
and the
perlguts(1) manpages.
- Use Perl from C++?
-
Read (at least)
the perlembed(1)
and the
perlguts(1) manpages.
