Demonstrates the AppendArrayCopy function.

Note: This example requires Chilkat v9.5.0.82 or above.

#include <C_CkJsonObjectW.h>

void ChilkatSample(void)
    {
    HCkJsonObjectW json;
    HCkJsonArrayW jarr;

    json = CkJsonObjectW_Create();
    CkJsonObjectW_Load(json,L"{ \"name\": \"John\", \"marbles\": 100 }");

    jarr = CkJsonArrayW_Create();
    CkJsonArrayW_Load(jarr,L"[ 1, 2, 3, \"apple\", \"orange\", [ 10, 20, 30 ], { \"name\": \"Alfred\"} ]");

    //  Copy the contents of jar to a new array member named "stuff".
    CkJsonObjectW_AppendArrayCopy(json,L"stuff",jarr);

    wprintf(L"%s\n",CkJsonObjectW_emit(json));
    //  Expected output is:  {"name":"John","marbles":100,"stuff":[1,2,3,"apple","orange",[10,20,30],{"name":"Alfred"}]}

    //  Note: The contents of the array were copied.
    //  If we modify the contents of jarr, it does not modify the array contained within "json" because it is a separate copy.
    //  For example:
    CkJsonArrayW_AddIntAt(jarr,-1,2020);
    wprintf(L"%s\n",CkJsonArrayW_emit(jarr));
    //  Expected output: [1,2,3,"apple","orange",[10,20,30],{"name":"Alfred"},2020]

    wprintf(L"%s\n",CkJsonObjectW_emit(json));
    //  Remains unchanged: {"name":"John","marbles":100,"stuff":[1,2,3,"apple","orange",[10,20,30],{"name":"Alfred"}]}


    CkJsonObjectW_Dispose(json);
    CkJsonArrayW_Dispose(jarr);
