[libvirt] libvirt boolean type

Hi. The following patch's intend is to get a discussion started first. Rationale: Many functions in libvirt return "1 for <TRUE>, 0 for <FALSE> and -1 on <ERROR>". When calling a function you need to read the documentation, skipping to the "Returns:" text in order to determine what return values to expect from the function and how to interpret them. This is cumbersome and takes an extra step which could be avoided. Advantages: + enum is binary compatible with int, so no ABI changes + without reading the documentation, you see what return values to expect at a glance + code generators in higher level languages could use it to generate proper wrappings to "boolean" automatically + compilers can probably warn when returning a value not part of the enum Claudio Bley (1): Implement a virBool type include/libvirt/libvirt.h.in | 25 +++++++++++++++++++++---- python/generator.py | 16 ++++++++++++++++ src/libvirt.c | 8 ++++---- 3 files changed, 41 insertions(+), 8 deletions(-) -- 1.7.9.5
