THREADENTRY32 

Describes an entry from a list that enumerates the threads executing in the system when a snapshot was taken.

typedef struct tagTHREADENTRY32{ 

    DWORD  dwSize;

    DWORD  cntUsage;

    DWORD  th32ThreadID;

    DWORD  th32OwnerProcessID;

    LONG   tpBasePri;

} THREADENTRY32;

typedef THREADENTRY32 *  PTHREADENTRY32;

typedef THREADENTRY32 *  LPTHREADENTRY32;

Members

dwSize

Specifies the length, in bytes, of the structure. Before calling the Thread32First1BRQYBN function, set this member to

sizeof(THREADENTRY32).

cntUsage

Number of references to the thread. A thread exists as long as its usage count is nonzero. As soon as its usage count becomes zero, a thread terminates.

th32ThreadID

Identifier of the thread. This identifier is compatible with the thread identifier returned by the CreateProcess5FBJ_XX function.

th32OwnerProcessID

Identifier of the process that created the thread. The contents of this member can be used by Win32 API elements.

tpBasePri

Initial priority level assigned to a thread. These values are defined:

THREAD_PRIORITY_IDLE

Indicates a base priority level of 1 for IDLE_PRIORITY_CLASS, NORMAL_PRIORITY_CLASS, or HIGH_PRIORITY_CLASS processes, and a base priority level of 16 for REALTIME_PRIORITY_CLASS processes.

THREAD_PRIORITY_LOWEST

Indicates 2 points below normal priority for the priority class.

THREAD_PRIORITY_BELOW_NORMAL

Indicates 1 point below normal priority for the priority class.

THREAD_PRIORITY_NORMAL

Indicates normal priority for the priority class.

THREAD_PRIORITY_ABOVE_NORMAL

Indicates 1 point above normal priority for the priority class.

THREAD_PRIORITY_HIGHEST

Indicates 2 points above normal priority for the priority class.

THREAD_PRIORITY_TIME_CRITICAL

Indicates a base priority level of 15 for IDLE_PRIORITY_CLASS, NORMAL_PRIORITY_CLASS, or HIGH_PRIORITY_CLASS processes, and a base priority level of 31 for REALTIME_PRIORITY_CLASS processes.

tpDeltaPri

Change in the priority level of a thread. This value is a signed delta from the base priority level assigned to the thread.

dwFlags

Reserved; do not use.
