             Summary: [patch]Nested functions aren't portable. Adapting RAII_VAR to use clang/llvm blocks to get the same/similar functionality.
                 Key: ASTERISK-23740
                 URL: https://issues.asterisk.org/jira/browse/ASTERISK-23740
             Project: Asterisk
          Issue Type: Bug
      Security Level: None
          Components: General
    Affects Versions: 11.1.0
         Environment: CLANG
            Reporter: Diederik de Groot
            Assignee: Rusty Newton


Nested functions are a GCC extension that is not sanctioned by C standards, thus the use of them is non-portable.  Specifically, CLANG does not support them.  CLANG is used by OSX, current versions of FreeBSD, and NetBSD is experimenting with it.  The RAII_VAR macro in include/asterisk/utils.h creates nested functions.  This prevents Asterisk 11.* from compiling with CLANG.
