Iterate over Matching Filenames

See more Zip Examples

Iterates over files within a .zip that match a pattern. In this case, the pattern is "*.pem". This example will open a .zip containing files of type .txt, .cer, .pem, and possibly others, and will iterate over only the .pem files. C++

#include <CkZip.h>
#include <CkZipEntry.h>

void ChilkatSample(void)
    {
    bool success = false;

    // This example requires the Chilkat API to have been previously unlocked.
    // See Global Unlock Sample for sample code.

    CkZip zip;

    // Open a .zip containing PEM files, among other things..
    success = zip.OpenZip("qa_data/certs/thawte-roots.zip");
    if (success == false) {
        std::cout << zip.lastErrorText() << "\r\n";
        return;
    }

    CkZipEntry entry;
    const char *pemStr = 0;
    const char *pattern = "*.pem";

    bool bHasMoreMatches = zip.EntryMatching(pattern,entry);
    while (bHasMoreMatches == true) {

        std::cout << "Entry: " << entry.fileName() << "\r\n";

        // Get the uncommpressed contents of the entry:
        pemStr = entry.unzipToString(0,"utf-8");
        std::cout << pemStr << "\r\n";

        bHasMoreMatches = entry.GetNextMatch(pattern);
    }
    }
