Demonstrates how to upload a file with user-defined metadata to the Amazon S3 service. C

#include <C_CkHttp.h>

void ChilkatSample(void)
    {
    BOOL success;
    HCkHttp http;
    const char *bucketName;
    const char *objectName;
    const char *localFilePath;
    const char *contentType;

    success = FALSE;

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

    http = CkHttp_Create();

    // Insert your AWS keys here:
    CkHttp_putAwsAccessKey(http,"AWS_ACCESS_KEY");
    CkHttp_putAwsSecretKey(http,"AWS_SECRET_KEY");

    bucketName = "chilkat.ocean";
    objectName = "seahorse.jpg";
    localFilePath = "qa_data/jpg/seahorse.jpg";
    contentType = "image/jpg";

    // User-defined metadata are name/value pairs, and are added to the HTTP request header.
    // Header names must begin with "x-amz-meta-" to distinguish them from other HTTP headers.
    // Note that Amazon S3 stores user-defined metadata keys in lowercase.

    // For example, to add genus=Hippocampus, we do this:
    CkHttp_SetRequestHeader(http,"x-amz-meta-genus","Hippocampus");

    // Add a few more user-metadata key pairs.
    CkHttp_SetRequestHeader(http,"x-amz-meta-species","big-belly seahorse");
    CkHttp_SetRequestHeader(http,"x-amz-meta-habitat","shallow tropical and temperate waters");

    success = CkHttp_S3_UploadFile(http,localFilePath,contentType,bucketName,objectName);

    if (success != TRUE) {
        printf("%s\n",CkHttp_lastErrorText(http));
    }
    else {
        printf("File uploaded.\n");

    CkHttp_Dispose(http);
