xdr_vector()--Translate between Arrays and Their XDR

Syntax

 #include <rpc/xdr.h>

 bool_t xdr_vector(XDR *xdrs,
                   char *arrp,
                   const u_int size,
                   const u_int elsize,
                   const xdrproc_t elproc);

  Threadsafe: No

The xdr_vector() function is a filter primitive that translates between fixed-length arrays and their corresponding external representations.

Parameters

xdrs (Input): A pointer to the eXternal Data Representation (XDR) stream handle.
arrp (I/O): The pointer to the array.
size (Input): The element count of the array.
elsize (Input): The byte size of each of the array elements.
elproc (Input): Translates between the C form of the array elements and their external representations. This parameter is an XDR filter.

Authorities

No authorization is required.

Return Value

TRUE (1)	Successful
FALSE (0)	Unsuccessful

Error Conditions

None.
