NTSTATUS SeAssignWorldSecurityDescriptor( IN PSECURITY_DESCRIPTOR SecurityDescriptor, IN OUT PULONG Length, IN PSECURITY_INFORMATION SecurityInformation ); Routine Description: This routine is called by the I/O system to properly initialize a security descriptor for a FAT file. It will take a pointer to a buffer containing an emptry security descriptor, and create in the buffer a self-relative security descriptor with Owner = WorldSid, Group = WorldSid. Thus, a FAT file is accessable to all. Arguments: SecurityDescriptor - Supplies a pointer to a buffer in which will be created a self-relative security descriptor as described above. Length - The length in bytes of the buffer. If the length is too small, it will contain the minimum size required upon exit. Return Value: STATUS_BUFFER_TOO_SMALL - The buffer was not big enough to contain the requested information.
