FSEEK(S)                 XENIX System V                  FSEEK(S)



     Name
          fseek, ftell, rewind - Repositions a file pointer in a
          stream.

     Syntax
          #include <stdio.h>

          int fseek (stream, offset, ptrname)
          FILE *stream;
          long offset;
          int ptrname;

          long ftell (stream)
          FILE *stream;

          void rewind(stream)
          FILE *stream;

     Description
          fseek sets the position of the next input or output
          operation on the stream.  The new position is at the signed
          distance offset bytes from the beginning, the current
          position, or the end of the file, according as ptrname has
          the value 0, 1, or 2.

          fseek undoes any effects of ungetc(S).

          After fseek or rewind, the next operation on an update file
          may be either input or output.

          ftell returns the current value of the offset relative to
          the beginning of the file associated with the named stream.
          The offset is measured in bytes.

          rewind(stream) is equivalent to fseek(stream, 0L, 0), except
          that no value is returned.

     Diagnostics
          fseek returns nonzero for improper seeks, otherwise zero.
