Expand description

Linux sys_fchmod implementation (stub)

Changes the permissions of a file using its file descriptor. This is a stub implementation that simply validates the file descriptor and returns success without actually changing permissions.

Arguments:

  • abi: LinuxRiscv64Abi context
  • trapframe: Trapframe containing syscall arguments
    • arg0: fd (file descriptor)
    • arg1: mode (new file permissions)

Returns:

  • 0 on success (if fd is valid)
  • usize::MAX (Linux -1) on error (if fd is invalid)
