QInt is a high-level data type that can be used to store integers and perform type-safe conversions. The following functions are available: - qint_from_int() Create a new QInt from an int - qint_from_int64() Create a new QInt from an int64_t - qint_to_int() Export QInt to int - qint_to_uint64() Export QInt to uint64_t - qint_to_uint32() Export QInt to uint32_t Signed-off-by: Luiz Capitulino <lcapitulino@redhat.com> --- Makefile | 1 + qint.c | 81 +++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ qint.h | 27 ++++++++++++++++++++ qobject.h | 1 + 4 files changed, 110 insertions(+), 0 deletions(-) create mode 100644 qint.c create mode 100644 qint.h
