  • File src/OFFile.m — part of check-in [fe2cbe0021] at 2018-04-22 16:13:04 on branch trunk — runtime: Define BOOL to be the same as bool

    As we define the ABI, we can just replace BOOL with bool everywhere,
    including in ObjFW itself. For the Apple platforms where BOOL and bool
    are different, this is not a problem as BOOL and bool are passed and
    returned the same way in the ABI.

    This still defines BOOL to bool for compatibility, except on AmigaOS and
    Wii, which both have its own BOOL type. (user: js, size: 10973) [annotate] [blame] [check-ins using]
