xdr_float()--Translate between Floats and Their XDR

 #include <rpc/xdr.h>

 bool_t xdr_float(XDR *xdrs,
                  float *fp);

The xdr_float() function is a filter primitive that translates between C-language floating-point numbers (normalized single floating-point numbers) and their external representations.

Parameters

xdrs  (Input) 

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

fp  (I/O) 

The address of the floating-point number.

Authorities

No authorization is required.

Return Value

Error Conditions

None.

The following example shows how xdr_float() is used:

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

typedef struct vector
{
        float x,y,z;
} vector ;

bool xdr_vector(XDR *xdrs, vector *p_vector)
{
        if(!xdr_float(xdrs,&(p_vector->x)))
                return FALSE;
        if(!xdr_float(xdrs,&(p_vector->y)))
                return FALSE;
        return xdr_float(xdrs,&(p_vector->z));
}
