【 在 zaction (cutebear) 的大作中提到: 】
Use API EnumProcesses
The EnumProcesses function retrieves the process identifier for each p
rocess object in the system.
BOOL EnumProcesses(
DWORD *lpidProcess, // array of process identifiers
DWORD cb, // size of array
DWORD *cbNeeded // number of bytes returned
);
Parameters:
lpidProcess
[out] Pointer to an array that receives the list of process identifier
s.
cb
[in] Specifies the size, in bytes, of the lpidProcess array.
cbNeeded
[out] Receives the number of bytes returned in the lpidProcess array.
Return Value:
If the function succeeds, the return value is nonzero.
If the function fails, the return value is zero. To get extended error
information, call GetLastError.
Remarks:
It is a good idea to give EnumProcesses a large array of DWORD values,
because it is hard to predict how many processes there will be at the
time you call EnumProcesses. To determine how many processes were enu
merated by the call to EnumProcesses, divide the resulting value in th
e cbNeeded parameter by sizeof(DWORD). There is no indication given wh
en the buffer is too small to store all process identifiers.
To obtain process handles for the processes whose identifiers you have
just obtained, call the OpenProcess function.
