fseek(3F)                                               fseek(3F)



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

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

     integer function ftell (lunit)

DESCRIPTION
     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      beginning of the file;
          1      the current position;
          2      the end of the file.

     The value returned by fseek will be 0 if successful, a sys-
     tem 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

NOTES
     When compiling source with the -Qocs option, an explicit
     underscore needs to be added to the end of the routine
     names.
