* sys/syscall.h — the raw syscall interface.
|
|
*
|
|
* syscall() is the ONLY place in nulsl-libc that talks the kernel ABI.
|
|
* Everything above it (read, write, exit, ...) is a wrapper.
|
|
*
|
|
* SYS_* constants below are the x86_64 numbers for the syscalls the libc
|
|
* itself wraps or its tests use. They are #ifndef-guarded so kernel UAPI
|
|
* headers can coexist. Extend the table as needed (docs/syscalls.md).
