How to use C Scope getpid() strcmp() in C++ mode

lucky6969b · 01-05-2006, 10:54 PM

I'd like to intermix some c/c++ code
I all have the extension of cpp
but getpid() and strcmp() were outside the scope
Could anybody help?
I used extern "C" { to no avail
the error mess
is simply
getpid not declared in this scope
etc
Thanks

what files are you including..

getpid() is in unistd.h according to the man page

all you should have to to is

#include <unistd.h>

and code like normal..

what about the strcmp function? the compiler was saying strcmp not declared in this scope. Thanks
