DESCRIPTION
XDR library routines allow C programmers to describe simple data structures in a machine-independent
fashion. Protocols such as remote procedure calls (RPC
) use these routines to describe the format of the
data.
These routines require the creation of XDR streams (see xdr_create (3N)).
Routines
See rpc(3N) for the definition of the
XDR data structure. Note that any buffers passed to the XDR rou-
tines must be properly aligned. It is suggested that malloc (3C) be used to allocate these buffers or that
the programmer insure that the buffer address is divisible evenly by four.
bool_t xdr_bool()
xdr_bool() translates between booleans (C integers) and their external representations. When
encoding data, this filter produces values of either 1 or 0. This routine returns TRUE if it succeeds,
FALSE otherwise.
bool_t xdr_char()
xdr_char() translates between C characters and their external representations. This routine
returns TRUE if it succeeds, FALSE otherwise. Note: encoded characters are not packed, and
occupy 4 bytes each. For arrays of characters, it is worthwhile to consider xdr_bytes(),
xdr_opaque(),orxdr_string() (see xdr_complex (3N)).
bool_t xdr_double()
xdr_double() translates between C double precision numbers and their external representa-
tions. This routine returns TRUE if it succeeds, FALSE otherwise.
bool_t xdr_enum()
xdr_enum() translates between C enum (actually integers) and their external representations.
