 getcontext.3

         Exemplar structure should use 'ucontext_t'.
-            In glibc we just finished a round of purging 'struct ucontext'
-            which is not in the POSIX reserved namespace of *_t tags. This has
-            some consequences to applications using the non-standard struct
-            ucontext:
-            https://sourceware.org/glibc/wiki/Release/2.26#Removal_of_.27struct_ucontext.27
-            but it also fixes a namespace conformance issue which is always a
-            longterm pain for large portable programs.
-
-            It was noted by Peter Maydell
-            (https://sourceware.org/bugzilla/show_bug.cgi?id=21457) that the
-            linux man pages still had references to 'struct ucontext' but only
-            in the form of an exemplar structure.
-
-            The patch fixes the exemplar to match what is in glibc
-            and therefore it won't ever suggest users can use 'struct
-            ucontext'.
