NAME
fstat - get status of open file
SYNOPSIS
(fstat = 28.)
(file descriptor in r0)
sys fstat; buf
fstat(fildes, buf)
struct inode *buf;
DESCRIPTION
This call is identical to stat, except that it operates on
open files instead of files given by name. It is most often
used to get the status of the standard input and output
files, whose names are unknown.
SEE ALSO
stat (II)
DIAGNOSTICS
The error bit (c-bit) is set if the file descriptor is
unknown; from C, a -1 return indicates an error, 0 indicates
success.
