NAME
nn_env - nanomsg environment variables
SYNOPSIS
Environment variables that influence the way nanomsg works
DESCRIPTION
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).
NOTES
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).
