Linux under OTL uses a long long type to support database bigint

The code is as follows:

#define Otl_bigint  Long long#define otl_str_to_bigint (str,n) {n=atoll (STR);} #define OTL_BIGINT_TO_STR (N,STR) {sprintf (STR, "%lld", n);} #include "otlv4.h"//include the OTL 4.0 header file

As can be seen from the above, OTL does not actually do what work, it is just a macro way to reserve the interface, the specific you own according to the operating system corresponding function implementation. Above is the implementation of Linux inside, Windows is another function, specific to check.
