I use libc-testsuite and test for fscanf function.

I found that the result is different from glibc.

In this case:

i = x = y = -1;

i = fscanf( "tmp.txt", "%5i%2i" , &x, &y)

printf(" i = %d, x = %d, y = %d" , i , x , y);

tmp.txt content >> "0x12 0x34"

In glibc, it will print >> "i = 2 , x = 18, y = 0"

In musl-libc will print >> "i = 1 , x = 18 , y = -1"

In this case, y's value should be "0x"

I wonder that "0x" is equal to "0" and should be counted as matched string or not?

It would be very helpful if you email me back and tell me what's the problem

Sorry with my poor english!
