calling perl from C/C++

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

Hello everyone,

just would like to know how to call perl script (module) from C/C++ ?

am not looking for any readymade module (which has licensing issues :o) ) 
but a very rudimentary way of calling perl modules from C, i can write wrappers on top of it.

cheers,
M

If it is truly a script you wish to call, then use the `system` or `fork()` & `exec()` functions in, IIRC, stdlib. A user level that continues to overstate my experience :-))	[reply] [d/l] [select]

You could use system (with STDERR/STDOUT redirected) or popen to communicate with an external perl process. The `system()` approach is more batch-like. You can later open (or tail) the output from the redirected streams. `popen()` would allow you to interact with the external perl process (reading/writing) while it is executed. Further issues to handle: buffering, timeouts, return-codes, security, permissions, ... Something along this demo: Read more... (2 kB)	[reply] [d/l] [select]
