Macro Definition Documentation

◆ EDT_API_LIBSHARED

#define EDT_API_LIBSHARED 1

By default, linking to a shared library is assumed. To link to a static library, users should define EDT_API_LIBSHARED=0 to disable shared library exports in header files.

◆ EDT_DEALLOCATE_WITH

#define EDT_DEALLOCATE_WITH ( x )

The memory allocated by the decorated function should be free'd by calling the function x.

GCC function attribute "malloc(<deallocator>)"

◆ EDT_STR_FORMAT_ATTR

#define EDT_STR_FORMAT_ATTR	(	archetype,
		fmt_string_index,
		first_to_check
	)	__attribute__((__format__(archetype, fmt_string_index, first_to_check)))

A wrapper for adding the 'format' function attribute to allow the compiler to type-check the format string and variadic arguments.

GCC function attribute "format"

Parameters

archetype	Style of formatting arguments, such as 'printf' or 'scanf'.
fmt_string_index	Function parameter index of the format string.
first_to_check	Function parameter index of the first variadic argument. Should be zero (0) for functions where arguments are not available to be checked.

◆ EDT_CHECK_RETURN

#define EDT_CHECK_RETURN __attribute__((__warn_unused_result__))

The caller should inspect the return value of the decorated function.

Dev note: Both the function declaration and definition should be decorated, for MSVC analysis.

GCC function attribute "warn_unused_result"
Microsoft Visual Studio property "_Check_return_" and warning C6031

◆ EDT_DEPRECATED_FUNC

#define EDT_DEPRECATED_FUNC	(	as_of_version,
		explanation
	)	__attribute__((__deprecated__(EDT_DEPRECATED_FUNC_MSG_(as_of_version, explanation))))

The decorated function is deprecated and may be removed in a future release.

GCC function attribute "deprecated"
Microsoft Visual Studio "__declspec(deprecated)" and warning C4996
