SHAllocShared.3w

NAME

SHAllocShared (SHLWAPI.7)

SYNOPSIS

HANDLE SHAllocShared
 (
  LPCVOID lpvData,
  DWORD   dwSize,
  DWORD   dwProcId
 )

DESCRIPTION

Create a block of sharable memory and initialise it with data.

PARAMS

lpvData [In] Pointer to data to write.

dwSize [In] Size of data.

dwProcId [In] Id of process owning data.

RETURNS

Success: A shared memory handle

Failure: NULL.

NOTES

Ordinals 7-11 provide a set of calls to create shared memory between a group of processes. The shared memory is treated opaquely in that its size is not exposed to clients who map it. This is accomplished by storing the size of the map as the first DWORD of mapped data, and then offsetting the view pointer returned by this size.

IMPLEMENTATION

Exported by ordinal only. Use GetProcAddress(3w) to obtain a pointer to the function.

Implemented in "dlls/shlwapi/ordinal.c".

Debug channel "shell".
