Norman Feske b078224753 Replace Genode::strncpy by Genode::copy_cstring - Since Genode::strncpy is not 100% compatible with the POSIX strncpy function, better use a distinct name. - Remove bogus return value from the function, easing the potential enforcement of mandatory return-value checks later.

README

LOG server that writes log messages onto a file system.

Log files are creating in a directory tree formed from session labels.
As an example the session label "init -> nitpicker" would create
a log file at "init/nitpicker.log".

The option to truncate files at the start of each LOG session is available
through session policy, as well the option to merge the logs of any
session matching a given policy. When a merged policy label contains a
trailing "->", the log filename takes the name of the next label element.

When a default-policy node specifies a merge, all sessions are merged into
the file "/log".

:Example configuration:
! <start name="log_file">
!   <resource name="RAM" quantum="1M"/>
!   <provides><service name="LOG"/></provides>
!   <config>
!     <policy label_prefix="nic_drv" truncate="no"/>
!     <policy label_prefix="runtime -> " merge="yes"/>
!     <default-policy truncate="yes"/>
!   </config>
! </start>
