xdr_float()--Translate between Floats and Their XDR

Syntax

 #include <rpc/xdr.h>

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

  Service Program Name: QZNFTRPC

  Default Public Authority: *USE

  Threadsafe: No

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

fp (I/O): The address of the floating-point number.

Authorities

No authorization is required.

Return Value

TRUE (1)	Successful
FALSE (0)	Unsuccessful

Error Conditions
