DEV_BROADCAST_PORT structure

Contains information about a modem, serial, or parallel port.

Syntax

typedef struct _DEV_BROADCAST_PORT {
  DWORD dbcp_size;
  DWORD dbcp_devicetype;
  DWORD dbcp_reserved;
  TCHAR dbcp_name[1];
} DEV_BROADCAST_PORT, *PDEV_BROADCAST_PORT;

Members

dbcp_size

The size of this structure, in bytes. This is the size of the members plus the actual length of the dbcp_name string (the null character is accounted for by the declaration of dbcp_name as a one-character array.)

dbcp_devicetype

Set to DBT_DEVTYP_PORT.

dbcp_reserved

Reserved; do not use.

dbcp_name

A null-terminated string specifying the friendly name of the port or the device connected to the port. Friendly names are intended to help the user quickly and accurately identify the device—for example, "COM1" and "Standard 28800 bps Modem" are considered friendly names.
