UNIMPLEMENTED(2) Linux Programmer's Manual UNIMPLEMENTED(2)NAME
afs_syscall, break, ftime, gtty, lock, mpx, phys, prof, profil, stty, ulimit - unimplemented system calls
SYNOPSIS
Unimplemented system calls.
DESCRIPTION
These system calls are not implemented in the Linux 2.0 kernel.
RETURN VALUE
These system calls always return -1 and set errno to ENOSYS.
NOTES
Note that ftime(3), profil(3) and ulimit(3) are implemented as library functions.
Some system calls, like ioperm(2), iopl(2), ptrace(2) and vm86(2) only exist on certain architectures.
Some system calls, like ipc(2) and {create,init,delete}_module(2) only exist when the Linux kernel was built with support for them.

I mean say for the user mode function read() there was a corresponding kernel mode function.
The system call index was fed in eax register and was... (2 Replies)
