QA·C Help - 0042

	0042	[Q] Definition of wchar_t differs from configured type.

QAC configuration

wchar_t is defined by a typedef in the standard library header files <stddef.h> and <stdlib.h>.

QA·C has an option (-intrinsictype, compiler personality), which allows the type associated with wide characters to be configured. Message 0042 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_WCHAR_T, when declaring the type of wchar_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 wchar_t, you should ensure that QA·C is configured to be consistent with this typedef.
