xdr_bool()--Translate between Booleans and Their XDR

 #include <rpc/xdr.h>

 bool_t xdr_bool(XDR *xdrs,
                 bool_t *bp);

The xdr_bool() function is a filter primitive that translates between Booleans (C integers) and their external representations. When encoding data, this filter produces values of either 1 or 0.

Parameters

xdrs  (Input) 

A pointer to the eXternal Data Representation (XDR) stream handle.

bp  (I/O) 

The address of the Boolean data.

Authorities

No authorization is required.

Notes

Callers of the xdr_bool() function should ensure that bp points to a 4 byte location in memory. The ENUM(*INT) compiler option should be used when compiling code that calls xdr_bool() to ensure that enumerated data types are represented internally as integers. Failure to do so, may cause unexpected values to be encoded to the XDR data stream.

Return Value

Error Conditions

None.

The following example shows how xdr_bool() is used:

#include <stdio.h>
#include <types.h>
#include <xdr.h>

typedef struct node
{
        bool_t connected;
        bool_t visited;
} node ;

bool xdr_node(XDR *xdrs, node *p_node)
{
        if(!xdr_bool(xdrs,&(p_node->connected)))
                return FALSE;
        return xdr_bool(xdrs,&(p_node->visited));
}
