|
|
* A fair number of C++0x (or more accurately C++11) features are used in this
|
|
* library and as this project is used where I work on older compilers this
|
|
* file was created to help.
|
|
*
|
|
* C++ features and their workaround where not supported:
|
|
* \li lambda functions - disabled, these are only used in the test anyway.
|
|
* \li typesafe enums - replaced with enum where comparisons needed.
|
|
* \li nullptr - defined to null.
|
|
*
|
|
* As of the port to version 3.1 (libzmqpp version 1.1.0) this file will also
|
|
* be used to maintain compatablity with multiple versions of 0mq
