FSEEK(3F)               COMMAND REFERENCE               FSEEK(3F)



NAME
     fseek, ftell - reposition a file on a logical unit

SYNOPSIS
     integer function fseek (lunit, offset, from)
     integer lunit, offset, from

     integer function ftell (lunit)
     integer lunit

DESCRIPTION
     Fseek repositions a file accociated with a logical unit.
     Lunit must refer to an open logical unit.  Offset is an
     offset in bytes relative to the position specified by from.
     Valid values for from are:

          0 meaning beginning of the file
          1 meaning the current position
          2 meaning the end of the file

     The value returned by fseek will be 0 if successful, and is
     a system error code otherwise.  (See perror(3f).)

     Ftell returns the current position of the file associated
     with the specified logical unit, lunit. The value is an
     offset, in bytes, from the beginning of the file.  If the
     value returned is negative, it indicates an error and will
     be the negation of the system error code. (See perror(3f).)

FILES
