nn_env - nanomsg environment variables
Environment variables that influence the way nanomsg works
This functionality is experimental and a subject to change at any time
Following environment variables are used to turn on some debugging for any
nanomsg application. Please, do not try to parse output and do not build
business logic based on it.
NN_PRINT_ERRORS
If set to a non-empty string nanomsg will print errors to
stderr. Some errors will be resolved by nanomsg itself (e.g. if nanomsg
can’t establish connection it will retry again in a moment). Some
depend on the environment (e.g. port that is bound by another process need to
be released). In any case nanomsg will not repeat the error message until
error is clear and appear again (e.g. connection established then broken
again).
The output of the debugging facility (NN_PRINT_ERRORS) is intended for reading
by a human and a subject for change at any time (even after 1.0 release).
