Retrieves a list of the processes attached to the current console.

DWORD WINAPI GetConsoleProcessList(
  _Out_ LPDWORD lpdwProcessList,
  _In_  DWORD   dwProcessCount
);

lpdwProcessList [out]
A pointer to a buffer that receives an array of process identifiers upon success. This must be a valid buffer and cannot be NULL. The buffer must have space to receive at least 1 returned process id.

dwProcessCount [in]
The maximum number of process identifiers that can be stored in the lpdwProcessList buffer. This must be greater than 0.

If the function succeeds, the return value is less than or equal to dwProcessCount and represents the number of process identifiers stored in the lpdwProcessList buffer.

If the buffer is too small to hold all the valid process identifiers, the return value is the required number of array elements. The function will have stored no identifiers in the buffer. In this situation, use the return value to allocate a buffer that is large enough to store the entire list and call the function again.

If the return value is zero, the function has failed, because every console has at least one process associated with it. To get extended error information, call GetLastError.

If a NULL process list was provided or the process count was 0, the call will return 0 and GetLastError will return ERROR_INVALID_PARAMETER. Please provide a buffer of at least one element to call this function. Allocate a larger buffer and call again if the return code is larger than the length of the provided buffer.

To compile an application that uses this function, define _WIN32_WINNT as 0x0501 or later. For more information, see Using the Windows Headers.
