Now that most places in the code use the ARRAY_SIZE macro instead of
coding it by hand, let's use some type safety in its definition. This is
a C++ version of similar macros used in kmod, Linux kernel and the
source of them, ccan.
A C++ version like this is used in V8 (the JS engine) and other open
source projects.
The main benefit of this version is that you get a compile error if you
pass in a variable that's not an array. For example,
Bla y[10];
Bla *y_ptr = y;
void foo(Bla x[])
{
// build error since x[] decay to a pointer in function
// parameter
for (int i = 0; i < ARRAY_SIZE(x); i++) {
...
}
// build error since y_ptr is not an array
for (int i = 0; i < ARRAY_SIZE(y_ptr); i++) {
...
}
}
I added the additional specialization to allow arrays of size 0.
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.
- libraries/AP_Common/AP_Common.h: Use bit 2 of Location.options to store
loiter direction
- ArduPlane/defines.h: New bitmask MASK_OPTIONS_LOITER_DIRECTION for struct
Location bit 2
- ArduPlane/ArduPlane.pde: New variable loiter_direction
- ArduPlane/GCS_Mavlink.pde: For mavlink loiter-commands use sign of param3 to
detemine direction. Set Location.option flag accordingly
- ArduPlane/commands.pde: Make sure loiter-directions get saved into EEPROM
correctly
- ArduPlane/commands_logic.pde: Set loiter_direction on all loiter-actions
as well as RTL/instant loiter
- ArduPlane/navigation.pde: Yield loiter_direction in update_loiter
