Subject: Fix: create_output_path() relayd util is not const-correct
X-Git-Url: http://git.efficios.com/?p=lttng-tools.git;a=commitdiff_plain;h=753871f3b4487af73ffe955783dba4f11960c3d3

Fix: create_output_path() relayd util is not const-correct

Code using this utility assumes that the path name passed to
this function is not modified. Using 'const' enforces this
assumption.

Moreover, this change makes it easier to write const-correct
code in the relayd.
