QNX Neutrino does not use block and character device nodes for access to device drivers; instead, it relies on device drivers to register as resource managers. Therefore, mknod() is restricted to creating files, directories, and FIFOs. The helper function iofunc_mknod() checks for write access in the parent directory.
