The change mostly affects code that formats strings using types provided by ``<inttypes.h>``. Users will need to replace placeholders such as ``%i`` and ``%x`` with ``PRIi32`` and ``PRIxx`` respectively.
The change mostly affects code that formats strings using types provided by ``<inttypes.h>``. When using these fixed-width types (e.g. ``uint32_t```), users will need to replace placeholders such as ``%i`` and ``%x`` with ``PRIi32`` and ``PRIx32`` respectively. Types *not* defined in ``<inttypes.h>`` (e.g. ``int``) do *not* need this special formatting.
In other cases, it should be noted that enums have the ``int`` type.
