Member Function Documentation

INT32 NativeExportDC::OutputRawBinary (  BYTE *  Data, UINT32  Length, UINT32  Alignment = 1 )  [virtual]

Outputs a sequence of bytes as raw data. Author: Rik_Heywood (Xara Group Ltd) <camelotdev@xara.com> Date: 19/12/94 Parameters: Data  - pointer to the data to output. [INPUTS] Length - the number of bytes to output. Alignment - the byte alignment to use - it will pad the end of the data with 0 bytes if Length is not divisible by this parameter. Hence use 1 for no padding. Returns: The number of bytes output to the file, in terms of the source data, not in terms of the number of ASCII characters used to represent them. -1 => error occured while writing => ERROR1 Errors: Disk/file error => ERROR1 Reimplemented from KernelDC. Definition at line 2668 of file nativeps.cpp. { // Param to note how many bytes we are writing out to the file INT32 nBytes = 0; // Start off with a blank line if (!OutputNewLine()) // Error encountered return -1; // Set the mode to binary //ExportFile.setMode(filebuf::binary); // Output a character to mark the begining of the binary section static TCHAR Begin = _T('>'); if (!OutputTCHARAsChar(&Begin, 1)) // Error return -1; // Output the line of binary data if (!OutputDirect(Data, Length)) { // Error return -1; } // We saved out 'Length' bytes there nBytes += Length; // Work out the padding needed ENSURE(Alignment != 0, "Bad alignment in OutputRawBinary!"); UINT32 Padding = Alignment - (Length % Alignment); if (Padding == Alignment) Padding = 0; if (Padding > 0) { // Put the string into a Buffer TCHAR Buffer[2]; Buffer[0] = 0; Buffer[1] = 0; // Output it however many times we need to while (Padding > 0) { if (OutputTCHARAsChar(Buffer, 1)) // Error return -1; nBytes++; Padding--; } } //output an end marker static TCHAR End = _T('<'); if (!OutputTCHARAsChar(&End, 1)) // Error return -1; // Set the mode to binary //ExportFile.setMode(filebuf::text); // All done return nBytes; }
