Prototype

    MCO_RET mco_lJSON_arr_add_uint(lews_JSON_context_h json_ctx, mco_uint8 value);

Arguments

Description

This function appends an unsigned numeric value to the current JSON array (e.g., adds 42 or 18446744073709551615 as an array element).

The value is converted to its decimal string representation and inserted without quotes, as required by the JSON standard.

The function may trigger a buffer flush and send data over the network if there is insufficient space in the output buffer to write the formatted number.

This function can only be called when the current context is inside a JSON array. Attempting to call it at the root level or inside a JSON object will result in an error.

    if (ret == MCO_S_OK) {
        ret = mco_lJSON_arr_add_uint(&json_ctx, 42);
        if (ret != MCO_S_OK) {
            printf("mco_lJSON_arr_add_uint error %d\n", ret);
        }
        ret = mco_lJSON_arr_add_uint(&json_ctx, 43);
        if (ret != MCO_S_OK) {
            printf("mco_lJSON_arr_add_uint error %d\n", ret);
        }
