[PATCH v3 06/36] libsepol: use logging framework in conditional.c

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Use the internal logging framework instead of directly writing to
stdout as it might be undesired to do so within a library.

Signed-off-by: Christian Göttsche <cgzones@xxxxxxxxxxxxxx>

v2:
   replace INFO calls by WARN since they are reasons of failure
