Which right result exactly ? My reading of MSDN suggests a negative return value. > defined __USE_MINGW_ANSI_STDIO macro. > But, if __USE_MINGW_ANSI_STDIO macro is defined - the result is 6. > Why? http://pubs.opengroup.org/onlinepubs/009695399/functions/snprintf.html Upon successful completion, the snprintf() function shall return the number of bytes that would be written to s had n been sufficiently large excluding the terminating null byte. So it seems return value of 6 corresponds to posix expectation. > > code: > #include <stdio.h> > int main() { > wchar_t buf[2]; > int len = snwprintf(buf, sizeof(buf) / 2, L"world!"); > printf("%d\n", len); > } > > > Thanks. > > ------------------------------------------------------------------------------ Live Security Virtual Conference Exclusive live event will cover all the ways today's security and threat landscape has changed and how IT managers can respond.
