This commit changes the way libraries headers are included in source files:
- If the header is in the same directory the source belongs to, so the
notation '#include ""' is used with the path relative to the directory
containing the source.
- If the header is outside the directory containing the source, then we use
the notation '#include <>' with the path relative to libraries folder.
Some of the advantages of such approach:
- Only one search path for libraries headers.
- OSs like Windows may have a better lookup time.
Check by false instead of checking by -1. Fix the following compiler warning
with gcc 5.1.0:
ardupilot/libraries/AP_Notify/ToneAlarm_Linux.cpp:64:13: warning: comparison of constant '-1' with boolean expression is always false [-Wbool-compare]
if (err == -1) {
^
Also change the initialization code not to use -1.
change parameter data type from const uint8_t to uint8_t,
initialise tonealarm error flag to value -1 at tonealarm class initiallisation
This is a part of a set of fixes for the bugs and typos tridge discovered and shared inside earlier commits for setting up tonealarm.
