xdr_getpos(3)                       CLIX                       xdr_getpos(3)



  NAME

    xdr_getpos, xdr_setpos - Library functions for external data
    representation

  LIBRARY

    Berkeley Software Distribution Library (libbsd.a)

  SYNOPSIS

    #include <sys/xdr.h>

    uint xdr_getpos(
      XDR *xdrs );

    xdr_setpos(
      XDR *xdrs ,
      uint pos );

  PARAMETERS

    xdrs   Specifies the address of the XDR handle.

    pos    Specifies the value to which an XDR stream's position is set.

  DESCRIPTION

    The xdr_getpos() and xdr_setpos() functions allow C programmers to
    describe arbitrary data structures in a machine-independent fashion.  Data
    for remote procedure calls are transmitted using these functions.

    The xdr_getpos() macro invokes the get-position function associated with
    the XDR stream, xdrs.  The function returns an unsigned integer that
    indicates the position of the XDR byte stream.

    The xdr_setpos() macro invokes the set-position function associated with
    the XDR stream xdrs.  The pos parameter is a position value obtained from
    xdr_getpos().

  CAUTIONS

    It is difficult to reposition some types of XDR streams, so xdr_setpos()
    may fail with one type of stream and succeed with another.

  RETURN VALUES

    The xdr_getpos() function returns the position of the XDR bytes stream.
    The xdr_setpos() function returns 1 if the XDR stream could be
    repositioned, and 0 otherwise.
