Translates between internal counted byte arrays and their external representations.
C Library (libc.a)
The xdr_bytes subroutine is a filter primitive that translates between counted byte arrays and their external representations. This subroutine treats a subset of generic arrays, in which the size of array elements is known to be 1 and the external description of each element is built-in. The length of the byte array is explicitly located in an unsigned integer. The byte sequence is not terminated by a null character. The external representation of the bytes is the same as their internal representation.
| Item | Description |
|---|---|
| xdrs | Points to the eXternal Data Representation (XDR) stream handle. |
| sp | Specifies the address of the pointer to the byte array. |
| sizep | Points to the length of the byte area. The value of this parameter cannot exceed the value of the maxsize parameter. |
| maxsize | Specifies the maximum number of bytes allowed when XDR encodes or decodes messages. |
Upon successful completion, this subroutine returns a value of 1. If unsuccessful, it returns a value of 0.
