Subject: Tracepoint probes don't need extern C
X-Git-Tag: v2.3.0-rc3~48
X-Git-Url: https://git.lttng.org/?p=lttng-tools.git;a=commitdiff_plain;h=02a1d793bcda3e75467878a46ef38dbb6e4ecaca

Tracepoint probes don't need extern C

tracepoint.h has the proper extern C guards, so every liblttng-ust API
called from the probe has the proper linkage.

The rest of the symbols are only meaningful within the probe, so we
don't care if they are mangled or not.

This fixes all UST applications in tests/

Fixes #597
