MgmGetMfe function (mgm.h)
The MgmGetMfe function retrieves a specific MFE.
Syntax
DWORD MgmGetMfe(
[in] PMIB_IPMCAST_MFE pimm,
[in, out] PDWORD pdwBufferSize,
[in, out] PBYTE pbBuffer
);
Parameters
[in] pimm
Pointer to a MIB_IPMCAST_MFE structure that specifies the MFE to retrieve. The information to be returned is indicated by the dwSource and dwGroup members of the MIB_IPMCAST_MFE structure.
[in, out] pdwBufferSize
On input, pdwBufferSize is a pointer to a DWORD-sized memory location that contains the size, in bytes, of the buffer pointed to by pbBuffer.
On output, if the return value is ERROR_INSUFFICIENT_BUFFER, pdwBufferSize receives the minimum size the buffer pointed to by pbBuffer must be to hold the MFE; otherwise the value of pdwBufferSize remains unchanged.
[in, out] pbBuffer
On input, the client must supply a pointer to a buffer.
On output, pbBuffer contains the specified MFE. The MFE is a MIB_IPMCAST_MFE structure.
Return value
If the function succeeds, the return value is NO_ERROR.
If the function fails, the return value is one of the following error codes.
| Value | Meaning |
|---|---|
|
Could not complete the call to this function. |
|
The specified buffer is too small to hold the MFE. The client should check the value of pdwBufferSize for the minimum buffer size required to retrieve the MFE. |
|
The specified MFE was not found. |
