Field Detail

dwSize

public WinDef.DWORD dwSize

The size of the structure, in bytes. Before calling the Process32First function, set this member to sizeof(PROCESSENTRY32). If you do not initialize dwSize, Process32First fails.

cntUsage

public WinDef.DWORD cntUsage

This member is no longer used and is always set to zero.

th32ProcessID

public WinDef.DWORD th32ProcessID

The process identifier.

th32DefaultHeapID

public BaseTSD.ULONG_PTR th32DefaultHeapID

This member is no longer used and is always set to zero.

th32ModuleID

public WinDef.DWORD th32ModuleID

This member is no longer used and is always set to zero.

cntThreads

public WinDef.DWORD cntThreads

The number of execution threads started by the process.

th32ParentProcessID

public WinDef.DWORD th32ParentProcessID

The identifier of the process that created this process (its parent process).

pcPriClassBase

public WinDef.LONG pcPriClassBase

The base priority of any threads created by this process.

dwFlags

public WinDef.DWORD dwFlags

This member is no longer used, and is always set to zero.

szExeFile

public char[] szExeFile

The name of the executable file for the process. To retrieve the full path to the executable file, call the Module32First function and check the szExePath member of the MODULEENTRY32 structure that is returned. However, if the calling process is a 32-bit process, you must call the QueryFullProcessImageName function to retrieve the full path of the executable file for a 64-bit process.

Method Detail

getFieldOrder

protected List getFieldOrder()

Description copied from class: Structure

Return this Structure's field names in their proper order. For example,

 protected List getFieldOrder() {
     return Arrays.asList(new String[] { ... });
 }
 

IMPORTANT When deriving from an existing Structure subclass, ensure that you augment the list provided by the superclass, e.g.

 protected List getFieldOrder() {
     List fields = new ArrayList(super.getFieldOrder());
     fields.addAll(Arrays.asList(new String[] { ... }));
     return fields;
 }
 

Field order must be explicitly indicated, since the field order as returned by Class.getFields() is not guaranteed to be predictable.

Specified by:

getFieldOrder in class Structure

Returns:

ordered list of field names
