sysarch — architecture-dependent system call
Standard C Library (libc, -lc)
#include <machine/sysarch.h> int sysarch(int number, void *args);
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.
See the manual pages for specific architecture-dependent system calls for information about their return values.
