ocaml-unix-errno

ocaml-unix-errno provides an errno variant similar to Unix.error but including POSIX 2008, Linux, OS X, and FreeBSD constructors. A macro definition type, defns is also provided in order to transport a specific errno-integer map as is the case with FUSE or 9p2000.u. The types and their functions reside in Errno and are independent of any Unix bindings. This makes the library's types usable from MirageOS on top of Xen. Errno_unix provides maps to and from Unix.error, the present host's errno map, an errno exception Error, and higher-order errno checking functions.

The executable errno-map will output a tab-delimited map from errno macro name to integer. This map can then be read back using the function Errno.defns_of_string.

You can’t perform that action at this time.
