• File src/tlskey.h — part of check-in [49aee5736e] at 2020-01-25 20:04:54 on branch trunk — tlskey.m: Use hashtable from runtime on AmigaOS

  tlskey.m used OFMapTable only on AmigaOS. This became a problem when
  autorelease pools were moved into the runtime, as autorelease pools use
  TLS. The build then broke, as there suddenly was a dependency from the
  runtime on ObjFW.

  This now uses the hashtable from the runtime and also no longer uses
  OFList, thus fixing the build. As we always use the runtime on AmigaOS
  anyway, this is fine. (user: js, size: 2046) [annotate] [blame] [check-ins using] [more...]
