lpFileName
Specifies the name (relative or full path) of the virtual file to be created.
dwDesiredAccess
Specifies the type of access requested to the virtual file (read, write, etc.).
dwShareMode
Specifies the sharing mode of the virtual file.
lpSecurityAttributes
Pointer to a SECURITY_ATTRIBUTES structure that optionally specifies a security descriptor and determines whether the file handle can be inherited by child processes.
Currently, BoxedApp ignores this parameter.
dwCreationDisposition
Specifies the action to take on a virtual file that already exists or does not exist.
dwFlagsAndAttributes
Combination of FILE_FLAG_* and FILE_ATTRIBUTE_* values. You can pass 0.
