This commit adds int64 support for cjson. To enable int64, you need to define the macro ENABLE_INT64. To make it more clear, you need to build cjson like this if you are using makefile:
mkdir build
cd build
cmake -DENABLE_INT64=ON ..
make
This implementation changed the type of valueint in struct cJSON: from int to long long(int64), and added a new flag cJSON_IsInt64.
For a int64 cJSON item, the value of item->type would be cJSON_Number | cJSON_IsInt64.
The existing functions parse_number and print_number can handle int64 now.
Considering we have added a new type cJSON_IsInt64, some new functions have been added:
CJSON_PUBLIC(long long *) cJSON_GetInt64NumberValue(cJSON * const item)
CJSON_PUBLIC(cJSON_bool) cJSON_IsInt64Number(const cJSON * const item)
CJSON_PUBLIC(cJSON *) cJSON_CreateInt64Number(long long integer)
CJSON_PUBLIC(cJSON*) cJSON_AddInt64NumberToObject(cJSON * const object, const char * const name, const long long integer)
CJSON_PUBLIC(long long) cJSON_SetInt64NumberValue(cJSON * const object, const long long integer)
And some existing functions are also adjusted for int64, including parse_number, cJSON_SetNumberHelper, print_number, cJSON_CreateNumber, cJSON_Compare and compare_json(in cJSON_Utils).
Besides the code changes, we have also added some testcases for int64.
These tests will run if ENABLE_INT64 is turned on.
