C++ TMsvEntry::Parent方法代码示例

/**
Creates a new entry as a child of the current context.

Ownership of the created entry is given to the process with the specified SID.

The parent ID and entry ID are set by the Message Server.

@param	aEntry
Index entry value for the new entry

@param	aOwnerId
The SID of the process that will own the create entry.

@param aBulk
A boolean value to indicate whether this is part of a bulk operation. (ETrue = bulk)

@return
KErrNone - success; KErrNoMemory - a memory allocation failed;
KErrNotSupported - aEntry is invalid
