NAME

     sysarch — architecture-dependent system call

LIBRARY

     Standard C Library (libc, -lc)

SYNOPSIS

     #include <machine/sysarch.h>

     int
     sysarch(int number, void *args);

DESCRIPTION

     The sysarch() system call performs the architecture-dependent function specified by number with the
     arguments specified by the args pointer.  The args argument is a pointer to a structure defining the actual
     arguments of the function.  Symbolic constants and argument structures for the architecture-dependent
     functions can be found in the header file <machine/sysarch.h>.

     The sysarch() system call should never be called directly by user programs.  Instead, they should access
     its functions using the architecture-dependent library.

RETURN VALUES

     See the manual pages for specific architecture-dependent system calls for information about their return
     values.
