The DynamicPluginMeta structure defines the type of dynamic module (preprocessor, rules, or detection engine), the version information, and path to the shared library. A shared library can implement all three types, but typically is limited to a single functionality such as a preprocessor. It is defined in sf_dynamic_meta.h as:
#define MAX_NAME_LEN 1024 #define TYPE_ENGINE 0x01 #define TYPE_DETECTION 0x02 #define TYPE_PREPROCESSOR 0x04 typedef struct _DynamicPluginMeta { int type; int major; int minor; int build; char uniqueName[MAX_NAME_LEN]; char *libraryPath; } DynamicPluginMeta;
