MACROS

11       The following preprocessor macros can be used to perform various checks
12       based on the version of the library you are compiling against. This may
13       be  useful if you only want to enable a feature on a certain version of
14       the library.

SYNOPSIS

17          #define BSON_CHECK_VERSION(major, minor, micro)
18
19          #define BSON_MAJOR_VERSION (1)
20          #define BSON_MINOR_VERSION (4)
21          #define BSON_MICRO_VERSION (1)
22          #define BSON_VERSION_S "1.4.1"
23
24          #define BSON_VERSION_HEX                                  \
25             (BSON_MAJOR_VERSION << 24 | BSON_MINOR_VERSION << 16 | \
26              BSON_MICRO_VERSION << 8)
