PROCESSENTRY32 (Windows CE 5.0)
This structure describes an entry from a list that enumerates the processes residing in the system address space when a snapshot was taken.
typedef struct tagPROCESSENTRY32 { DWORD dwSize; DWORD cntUsage; DWORD th32ProcessID; DWORD th32DefaultHeapID; DWORD th32ModuleID; DWORD cntThreads; DWORD th32ParentProcessID; LONG pcPriClassBase; DWORD dwFlags; TCHAR szExeFile[MAX_PATH]; DWORD th32MemoryBase;DWORD th32AccessKey;} PROCESSENTRY32; typedef PROCESSENTRY32* PPROCESSENTRY32; typedef PROCESSENTRY32* LPPROCESSENTRY32;
Members
dwSize
Length, in bytes, of the structure.Before calling the Process32First function, set this member to sizeof(PROCESSENTRY32).
If you do not initialize dwSize, Process32First fails.
cntUsage
Number of references to the process.Must be 1.
th32ProcessID
Identifier of the process.The contents of this member can be used by Win32 API elements.
th32DefaultHeapID
Identifier of the default heap for the process.The content of this member has meaning only to the tool help functions.
This member is not a handle, nor is it usable by Win32 API elements.
th32ModuleID
Module identifier of the process.Must be 0.
cntThreads
Number of execution threads started by the process.th32ParentProcessID
Identifier of the process that created the process being examined.Must be 0.
pcPriClassBase
Base priority of threads created by this process.Value is always THREAD_PRIORITY_NORMAL
dwFlags
Reserved; do not use.szExeFile
Null-terminated string that contains the path and file name of the executable file for the process.th32MemoryBase
Load address of the executable file.th32AccessKey
Array of bits.Each bit signifies permission to see the address space of one process.
For the PROCESSENTRY32 structure, the key contains the bit required to see that address space.
Remarks
All strings are Unicode.
To use the process and thread identifiers with GetThreadTimes and other functions that take process handles, the identifiers can be cast directly to process and thread handles. However, accessing PROCESSENTRY32 for other processes requires using the SetProcPermissions function to enable access to the other process's slot.
Requirements
OS Versions: Windows CE 1.0 and later.
Header: Tlhelp32.h.
