The entLogicalTable.h header file contains the typedef for the entLogicalEntry_tstructure. This structure is representative of the entLogicalTable columns that are defined in RFC 2737. The entLogicalEntry_t is defined as follows:
typedef struct entLogicalEntry_s {
int_l entLogicalIndex;
char *entLogicalDescr;
oid *entLogicalType;
int_l entLogicalTypeSize;
char *entLogicalCommunity;
char *entLogicalTAddress;
oid *entLogicalTDomain;
int_l entLogicalTDomainSize;
char *entLogicalContextEngineId;
char *entLogicalContextName;
struct entLogicalEntry_s* pNextEntry;
} entLogicalEntry_t;
