Enumeration Type Documentation

latch_mode_t

enum latch_mode_t

Increasing values indicate increasing degrees of privilege; that is lock mode l, l>k, allows at least as many operations as mode k. I.e., EX > SH > Q > NL.

If you alter this, also change the corresponding interface and definition of latch_mode_str.
