xdr_wrapstring()--Call the xdr_string() Function

Syntax

 #include <rpc/xdr.h>

 bool_t xdr_wrapstring(XDR *xdrs,
                       char **sp);

  Service Program Name: QZNFTRPC

  Default Public Authority: *USE

  Threadsafe: No

The xdr_wrapstring() function is a primitive that calls the xdr_string(xdr, sp, maxuint) API, where maxuint is the maximum value of an unsigned integer. The xdr_wrapstring() is useful where a translation of xdrproc_t is required. xdrproc_t has only two parameters while the xdr_string() function requires three.

Parameters

xdrs (Input): A pointer to the External Data Representation (XDR) stream handle.
sp (I/O): The address of the pointer to the string. If decoding and *sp==NULL, XDR allocated memory for the decoded string.

Authorities

No authorization is required.

Return Value

TRUE (1)	Successful
FALSE (0)	Unsuccessful

Error Conditions

None.

bool_t xdr_address(XDR *xdrs, address *p_address)
{
        if!(xdr_wrapstring(xdrs,&(p_address->street)))
                return FALSE;
        if(!xdr_int(xdrs,&(p_address->number)))
                return FALSE;
        return xdr_int(xdrs,&(p_address->apartment));
}
