NAME wchar_t_to_netcs - Converts international character data from a local code set to a network code set Used by client and server applications. SYNOPSIS #include <dce/codesets_stub.h> void wchar_t_to_netcs( rpc_binding_handle_t binding, unsigned32 network_code_set_value, wchar_t *local_data, unsigned32 local_data_length, idl_byte *network_data, unsigned32 *network_data_length, error_status_t *status ); PARAMETERS Input binding Specifies the target binding handle from which to obtain code set conversion information. When called from the client stub, this value is the binding handle of a compatible server returned by the rpc_ns_binding_import_next() or rpc_ns_binding_select() routine. When called from the server stub, this value is a pointer to binding information that the client stub passed in the RPC call. network_code_set_value The registered hexadecimal integer value that represents the code set to be used to transmit character data over the network. In general, the "network" code set is the code set that the client application's code sets evaluation routine has determined to be compatible for this client and server. When the caller is the client stub, this value is the sending tag. When the caller is the server stub, this value is the receiving tag. local_data A pointer to the international character data to be transmitted, in the local code set encoding. local_data_length The number of wchar_t data elements to be converted. For a varying array or a conformant varying array, this value is the local value of the length_is variable. For a conformant array, this value is the local value of the size_is variable. For a fixed array, the value is the array size specified in the interface definition. Output network_data A pointer to the converted data, in idl_byte format. network_data_length A pointer to the length of the converted data, in units of idl_byte. Specify NULL if a fixed or conformant array is to be converted. status Returns the status code from this routine. This status code indicates whether the routine completed successfully or, if not, why not. The possible status codes and their meanings are as follows: rpc_s_ok Success. rpc_s_ss_incompatible_codesets The specified code set does not match the code set specified in the sending tag in the binding handle. If this error occurs in the server stub, an exception is raised to the client application. When this routine is running the host converter routines, the following errors can be returned: rpc_s_ss_invalid_char_input rpc_s_ss_short_conv_buffer rpc_s_ss_iconv_error (HP-UX reference platform only) rpc_s_ss_no_memory (HP-UX reference platform only) When invoked from the server stub, this routine calls the dce_cs_loc_to_rgy() routine and host converter routines. If any of these routines returns an error, an exception is raised to the client application. DESCRIPTION The wchar_t_to_netcs() routine belongs to a set of DCE RPC routines for use by client and server applications that are transferring international character data in a heterogeneous character set and code sets environment. The wchar_t_to_netcs() routine is one of the DCE RPC stub code set conversion routines that RPC stubs use before they marshall or unmarshall data to convert international character data to and from local and network code sets. Client and server stubs call the wchar_t_*_netcs() routines when the wchar_t type has been specified as the local data type with the cs_char attribute in the attribute configuration file for the application. Client and server stubs call the wchar_t_to_netcs() routine before they marshall any data. The routine takes a binding handle, a code set value that identifies the code set to be used to transfer international character data over the network, the address of the data that may need to be converted, and the length of the data, in units of wchar_t. The routine first converts the character data from wchar_t values to idl_byte values. The routine next compares the sending code set to the local code set currently in use. If the routine finds that code set conversion is necessary, (because the local code set differs from the code set specified to be used on the network), it determines which host code set converter to call to convert the data and then invokes that converter. The routine then returns the converted data, in units of idl_byte. If the data is a varying, conformant, or conformant varying array, the routine also returns the length of the converted data, in units of idl_byte. Applications can specify local data types other than cs_byte and wchar_t (the local data types for which DCE RPC supplies stub support routines for code set conversion) with the cs_char ACF attribute. In this case, the application must also supply local_type_to_netcs() and local_type_from_netcs() stub conversion routines for the application- defined local type.
