Not all users match that model, but quite a few do. No mindless
mass conversions, please...
Added:
CLASS(filename, name)(user_path) =>
getname(user_path)
CLASS(filename_kernel, name)(string) =>
getname_kernel(string)
CLASS(filename_flags, name)(user_path, flags) =>
getname_flags(user_path, flags)
CLASS(filename_uflags, name)(user_path, flags) =>
getname_uflags(user_path, flags)
CLASS(filename_maybe_null, name)(user_path, flags) =>
getname_maybe_null(user_path, flags)
CLASS(filename_complete_delayed, name)(delayed) =>
complete_getname(delayed)
CLASS(filename_consume, name)(filename) =>
no_free_ptr(filename)
all with putname() as destructor.
"flags" in filename_flags() is in LOOKUP_... space, only LOOKUP_EMPTY matters.
"flags" in filename_uflags() and filename_maybe_null() is in AT_...... space,
and only AT_EMPTY_PATH matters.
These conventions might be worth reconsidering...
