Add Binary Data to a ZIP Using AddBd

See more Zip Examples

This example demonstrates how to use the AddBd method to add binary data from a BinData object as a file entry within a ZIP archive.

The data is created entirely in memory, added to the ZIP as data/binary.dat, and then written to disk.

C

#include <C_CkZip.h>
#include <C_CkBinData.h>

void ChilkatSample(void)
    {
    BOOL success;
    HCkZip zip;
    HCkBinData bd;

    success = FALSE;

    //  Create a new ZIP archive.
    zip = CkZip_Create();

    success = CkZip_NewZip(zip,"inMemoryData.zip");
    if (success == FALSE) {
        printf("%s\n",CkZip_lastErrorText(zip));
        CkZip_Dispose(zip);
        return;
    }

    //  Create a BinData object containing binary content.
    bd = CkBinData_Create();

    //  Append some bytes as hexadecimal.
    //  The decoded bytes will become the contents of the ZIP entry.
    success = CkBinData_AppendEncoded(bd,"000102030405060708090A0B0C0D0E0F","hex");
    if (success == FALSE) {
        printf("%s\n",CkBinData_lastErrorText(bd));
        CkZip_Dispose(zip);
        CkBinData_Dispose(bd);
        return;
    }

    //  Add the BinData contents as a file entry within the ZIP.
    //  The file will be stored as "data/binary.dat" inside the ZIP archive.
    success = CkZip_AddBd(zip,"data/binary.dat",bd);
    if (success == FALSE) {
        printf("%s\n",CkZip_lastErrorText(zip));
        CkZip_Dispose(zip);
        CkBinData_Dispose(bd);
        return;
    }

    //  Write the ZIP archive to disk and close it.
    success = CkZip_WriteZipAndClose(zip);
    if (success == FALSE) {
        printf("%s\n",CkZip_lastErrorText(zip));
        CkZip_Dispose(zip);
        CkBinData_Dispose(bd);
        return;
    }

    printf("ZIP archive created successfully.\n");


    CkZip_Dispose(zip);
    CkBinData_Dispose(bd);
