Provides pointer chasing within structures and serializes null pointers.
C Library (libc.a)
xdr_pointer (xdrs, objpp, objsize, xdrobj) XDR *xdrs; char **objpp; u_int objsize; xdrproc_t xdrobj;
The xdr_pointer subroutine provides pointer chasing within structures and serializes null pointers. This subroutine can represent recursive data structures, such as binary trees or linked lists.
|xdrs||Points to the eXternal Data Representation (XDR) stream handle.|
|objpp||Points to the character pointer of the data structure.|
|objsize||Specifies the size of the structure.|
|xdrobj||Specifies the XDR filter for the object.|
Upon successful completion, this subroutine returns a value of 1. If unsuccessful, it returns a value of 0.
This subroutine is part of Base Operating System (BOS) Runtime.
