Bug #: 11789
Summary: STR2WSTR(__FUNCTION__) should work in microsoft mode
Product: clang
Version: unspecified
Platform: PC
OS/Version: Windows NT
Status: NEW
Severity: enhancement
Priority: P
Component: Driver
AssignedTo: [email protected]
ReportedBy: [email protected]
CC: [email protected]
Classification: Unclassified
#include <stdio.h>
#define _FOO_STR2WSTR(s) L##s
#define FOO_STR2WSTR(s) _FOO_STR2WSTR(s)
int main() {
//const wchar_t* kFoo = L__FUNCTION__; // doesn't work in cl.exe
const wchar_t* kWFoo = FOO_STR2WSTR(__FUNCTION__); // works in cl
}
Both gcc and clang don't allow this, but cl.exe does. (gcc and clang support it
for e.g. __FILE__.)
This is used in msvc's c++ standard headers.
