|
2002-12-18 09:22:32 +00:00
|
|
|
The
|
|
|
|
|
.Fn sysarch
|
|
|
|
|
system call
|
1998-07-28 03:39:04 +00:00
|
|
|
performs the architecture-dependent function
|
|
|
|
|
specified by
|
|
|
|
|
.Fa number
|
|
|
|
|
with the arguments specified by the
|
|
|
|
|
.Fa args
|
|
|
|
|
pointer.
|

|
The
|
|
|
|
|
.Fa args
|
|
|
|
|
argument
|
1998-07-28 03:39:04 +00:00
|
|
|
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
|
2003-09-10 19:24:35 +00:00

|
.Pp
|
|
|
|
|
The
|
|
|
|
|
.Fn sysarch
|
|
|
|
|
system call should never be called directly by
|
2004-07-02 23:52:20 +00:00
|
|
|
user programs.
|
|
|
|
|
Instead, they should access
|
1998-07-28 03:39:04 +00:00
|
|
|
its functions using the architecture-dependent
|
|
|
|
|
library.
