QA·C Help - 0041

	0041	[Q] Definition of ptrdiff_t differs from configured type.

QAC configuration

ptrdiff_t is defined by a typedef in the standard library header file <stddef.h>.

QA·C has an option (-intrinsictype, compiler personality), which allows the type associated with a pointer subtraction operation to be defined. Message 0041 is generated if a typedef encountered in the source code is not consistent with this configured type.

The QA C Standard Library header files use an implicit macro, PRQA_PTRDIFF_T, when declaring the type of ptrdiff_t. This macro is automatically defined in the QA·C environment to reflect the configuration option setting. If you are using your own header files to define ptrdiff_t, you should ensure that QA·C is configured to be consistent with this typedef.
