source: trunk/zoo-project/zoo-kernel/service.h @ 905

Last change on this file since 905 was 889, checked in by knut, 6 years ago

Added some new logging functionality (function logMessage(), macros zooLog, zooLogMsg). Added utility functions setErrorMessage(), hasvalue(), and nonempty() in service.c. Added enum WPSException and arrays WPSExceptionText and WPSExceptionCode (see also function setErrorMessage). New conditional definition of type bool in service.c (to fix issue with bool). Null pointer check in function addToMap. Added missing return values and explicit type casts in some functions. Removed Windows-specific code in function dumpBackFinalFile (zoo_service_loader.c) that may cause error for async raw data output in formats other than XML.

  • Property svn:eol-style set to native
  • Property svn:mime-type set to text/x-chdr
