| ## idl_es_decode_buffer(3rpc) Returns a buffer decoding handle to the IDL encoding services Synopsis void idl_es_decode_buffer( idl_byte *encoded_data_buffer, idl_ulong_int buffer_size, idl_es_handle_t *es_handle, error_status_t *status); Parameters Input encoded_data_buffer The address of the buffer that contains the data to be decoded. buffer_size The number of bytes of data in the buffer to be decoded. Output es_handle Returns the address of an IDL encoding services handle for use by a client or server decoding operation. status Returns the status code from this routine. This status code indicates whether the routine completed successfully or, if not, why not. Description The IDL encoding services provide client and server RPC applications with a method for encoding data types in input parameters into a byte stream and decoding data types in output parameters from a byte stream without invoking the RPC runtime. Encoding and decoding operations are analogous to marshalling and unmarshalling, except that the data is stored locally, and is not transmitted over the network. Client and server applications can use the IDL encoding services to create persistent storage for their data. Encoding "flattens" complex data types into a byte stream for storage on disk, while decoding restores the flattened data to complex form. The idl_es_decode_buffer( ) routine belongs to a set of routines that return handles to the IDL encoding services for use by client and server encoding and decoding operations. The information in the handle controls the way in which the IDL encoding services manage memory when encoding or decoding data. The idl_es_decode_buffer( ) routine returns a buffer decoding handle, which directs the IDL encoding services to decode data from a single application-supplied buffer of encoded data. Return Values None. Errors The following describes a partial list of errors that might be returned. Refer to the OSF DCE Problem Determination Guide for complete descriptions of all error messages. rpc_s_ok Success. rpc_s_ss_bad_buffer Bad buffer operation. rpc_s_no_memory Insufficient memory available to complete operation.
