示例#1

文件： processPdf.cpp 项目： iroot/sopdf

int

    soPdfFile* inFile,
    soPdfFile* outFile
    )
{
    int retCode = 0;

    assert(inFile != NULL);

    // Open the input file
    retCode = openPdfFile(inFile);
    if (retCode != 0)

    // Create an output file
    retCode = newPdfFile(outFile);

    // Copy from source to destination
    retCode = copyPdfFile(inFile, outFile);
    if (retCode != 0)

Cleanup:
