SESSION_BUFFER structure (nb30.h)

[Netbios is not supported on Windows Vista, Windows Server 2008, and subsequent versions of the operating system]

The SESSION_BUFFER structure contains information about a local network session. One or more SESSION_BUFFER structures follows a SESSION_HEADER structure when an application specifies the NCBSSTAT command in the ncb_command member of the NCB structure.

Syntax

typedef struct _SESSION_BUFFER {
  UCHAR lsn;
  UCHAR state;
  UCHAR local_name[NCBNAMSZ];
  UCHAR remote_name[NCBNAMSZ];
  UCHAR rcvs_outstanding;
  UCHAR sends_outstanding;
} SESSION_BUFFER, *PSESSION_BUFFER;
