# sysarch(2freebsd)

architecture-dependent system call

## 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.
