Compress a String and Save as a Gzip File

See more Gzip Examples

This example demonstrates how to use the CompressStringToFile method to compress a string and write the result directly to a Gzip (.gz) file.

The input string is first converted to its byte representation using the specified character set (in this case, UTF-8). The resulting bytes are then compressed using the Gzip format, and the compressed output is written directly to the specified file.

This method is convenient when you want to generate a compressed file from in-memory text without needing intermediate objects such as BinData or StringBuilder.

C

#include <C_CkGzip.h>

void ChilkatSample(void)
    {
    BOOL success;
    HCkGzip gzip;
    const char *inputStr;

    success = FALSE;

    // This example demonstrates how to compress a string and save the result
    // directly to a Gzip (.gz) file.

    gzip = CkGzip_Create();

    // The string to be compressed:
    inputStr = "The quick brown fox jumps over the lazy dog.";

    // Compress the string using UTF-8 and write to a file:
    success = CkGzip_CompressStringToFile(gzip,inputStr,"utf-8","output.gz");
    if (success == FALSE) {
        printf("%s\n",CkGzip_lastErrorText(gzip));
        CkGzip_Dispose(gzip);
        return;
    }

    printf("Compression successful.\n");
    printf("Gzip file written to output.gz\n");


    CkGzip_Dispose(gzip);
