suggests that this is a problem on MinGW, but pI is supposed to be "I64" on that
platform, not "ll".
What warnings does your compiler generate for the following?
#include <stdio.h>
int a;
long long b;
int main (void) {
printf ("x=%0*llx\n", a, b);
printf ("x=%0*I64x\n", a, b);
return 0;
}
and what are __MINGW32__, __USE_MINGW_ANSI_STDIO, MINGW_W64,
__MINGW32_MAJOR_VERSION, __GNUC__, and __GNUC_MINOR__ on your platform?
On my Fedora 31 platform, the above program causes 'gcc -Wall' to say:
t.c: In function ‘main’:
t.c:6:17: warning: unknown conversion type character ‘I’ in format [-Wformat=]
6 | printf ("x=%0*I64x\n", a, b);
| ^
t.c:6:11: warning: too many arguments for format [-Wformat-extra-args]
6 | printf ("x=%0*I64x\n", a, b);
| ^~~~~~~~~~~~~
which is what I'd expect on Fedora.
