XIEITE_STDLIB_TYPE_/*???*/, XIEITE_STDLIB_MAJOR_/*???*/, XIEITE_STDLIB_MINOR_/*???*/, XIEITE_STDLIB_PATCH_/*???*/, XIEITE_STDLIB_EQ(), XIEITE_STDLIB_LEAST(), XIEITE_STDLIB_MOST()

 Defined in header <xieite/pp/stdlib.hpp>

Macros for identifying the current language and its version (major, minor, patch). The macros are not mutually exclusive.


Definitions

 #type 
#define XIEITE_STDLIB_TYPE_/*???*/ /* boolean integer literal */
#define XIEITE_STDLIB_MAJOR_/*???*/ /* integer literal */
#define XIEITE_STDLIB_MINOR_/*???*/ /* integer literal */
#define XIEITE_STDLIB_PATCH_/*???*/ /* integer literal */
Use with CLOUDABI_C, COMO_CPP, DINKUMWARE_CPP, GNU_C, GNU_CPP, IBM_VA_CPP, LLVM_CPP, METROWERKS_CPP, MODENA_CPP, PDP_C, ROGUEWAVE_CPP, SGI_CPP, UC_C, VMS_C, or Z_C. See example.

#eq 
#define XIEITE_STDLIB_EQ(type, major, .../* minor, patch */) /* boolean expression */
Allows two optional arguments for the minor and patch version numbers. Expands to an expression checking whether a language is in use and its version is equal to some value.

#least 
#define XIEITE_STDLIB_LEAST(type, major, .../* minor, patch */) /* boolean expression */
Expands to an expression checking whether a language is in use and its version is equal to or greater than some value.

#most 
#define XIEITE_STDLIB_MOST(type, major, .../* minor, patch */) /* boolean expression */
Expands to an expression checking whether a language is in use and its version is equal to or less than some value.


Example

 
int main() {
	std::println("Is standard library libstdc++? {}", XIEITE_STDLIB_TYPE_GNU_CPP);
}
Possible output: 
Is standard library libstdc++? 1
