Function: make-h_errno-condition h_errno

Build and return a new &h_errno condition object holding the given encoded h_errno value.

Function: h_errno-condition? obj

Return #t if obj is an instance of &h_errno.

Function: condition-h_errno obj

Accessor for the encoded h_errno value in obj, which must be an instance of &h_errno.
