FSTAT(II)                    8/5/73                     FSTAT(II)







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.
