Usage: $PROG [-n|-p] [-o filename] [-s syscall.h] object ...
|
|
-n Create SYSCALL_NOERROR.
|
|
-p Create PSEUDO_NOERROR.
|
|
(also removes leading "_" on syscall name).
|
|
-o filename Output to filename.
|
|
-s syscall.h Header to #include instead of <sys/syscall.h>.
|
|
|
|
The CPP environment variable must be set
|
|
to the path to the C preprocessor.
