/* Linux uses a negative return value to indicate syscall errors, unlike

most Unices, which use the condition codes' carry flag.
|

|
|
|
|
|

Since version 2.1 the return value of a system call might be negative
|
|
|
|
even if the call succeeded. E.g., the `lseek' system call might return
|
|
|
|
a large offset. Therefore we must not anymore test for < 0, but test
|
|
|
|
for a real error by making sure the value in %d0 is a real error

|
1996-11-14 02:04:01 +00:00
|

|
in -1 .. -4095 as a valid result so we can savely test with -4095. */

speed is more important, we don't use movem. Since %a0 and %a1 are
