.Sh NAME
-.Nm syscall ,
-.Nm __syscall
+.Nm syscall
.Nd indirect system call
.Sh SYNOPSIS
.In sys/syscall.h
.In unistd.h
.Ft int
.Fn syscall "int number" "..."
-.Fn __syscall "quad_t number" "..."
.Sh DESCRIPTION
.Fn syscall
performs the system call whose assembly language
Symbolic constants for system calls can be found in the header file
.In sys/syscall.h .
.Pp
-Since different system calls have different return types, a
-prototype of
-.Nm __syscall
-specifying the correct return type should be declared locally.
-This is especially important for system calls returning
-larger-than-int results.
-.Pp
-The
-.Nm __syscall
-form should be used when one or more of the parameters is a
-64-bit argument to ensure that argument alignment is correct.
-This system call is useful for testing new system calls that
-do not have entries in the C library.
.Sh RETURN VALUES
The return values are defined by the system call being invoked.
In general, for system calls returning
