9 Environment variables that influence the way nanomsg works

12 This functionality is experimental and a subject to change at any time

14 Following environment variables are used to turn on some debugging for
15 any nanomsg application. Please, do not try to parse output and do not
16 build business logic based on it.

18 NN_PRINT_ERRORS
19 If set to a non-empty string nanomsg will print errors to stderr.
20 Some errors will be resolved by nanomsg itself (e.g. if nanomsg
21 can’t establish connection it will retry again in a moment). Some
22 depend on the environment (e.g. port that is bound by another
23 process need to be released). In any case nanomsg will not repeat
24 the error message until error is clear and appear again (e.g.
25 connection established then broken again).
26
28 The output of the debugging facility (NN_PRINT_ERRORS) is intended for
29 reading by a human and a subject for change at any time (even after 1.0
30 release).
