How do I call system functions?

[ToddAndMargo]

Hi All,

In Linux, how do I call system functions from Perl 6?
int XStoreBytes(Display *display, char *bytes, int nbytes);

And what is that?  "C"?

Is there an inline "C" call?

Many thanks,
-T


man XStoreBuffer

NAME
       XStoreBytes, XStoreBuffer, XFetchBytes, XFetchBuffer,
       XRotateBuffers -  manipulate cut and paste buffers

SYNTAX

       int XStoreBuffer(Display *display, char *bytes, int nbytes, int buf‐
              fer);

       char *XFetchBytes(Display *display, int *nbytes_return);

       char *XFetchBuffer(Display *display, int *nbytes_return, int 
buffer);
