Hey there,
I'm trying to use perlxs to call a proprietry C library from my perl scripts.
I've gone through the tutorial and such, I've successfully got the extension compiling and I can use it in my perl script and even call a couple of the functions i've already defined in the .xs file.
The problem, however, is I can't figure out how to return a variable from one of the functions. Every way I define it in the .xs file either doesn't compile, or compiles and segfaults when i run the perl script.
The C excerpt I use to call this function is as follows :
char sError[BUFFLEN];
QAErrorMessage(error_code, sError, BUFFLEN);
BUFFLEN being defined as 256 or whatever.
It's supposed to return a nice, helpful error message in sError...
The function doesn't seem to like being called with a char *, and I have no idea how to make xs return the sError to perl as a normal scalar.
Any suggestions would be much appreciated
