The kernel version of sscanf() does not allow for scanning a string with
multiple concatenated integers even when maximum field widths are specified to
stop reading the string to delineate the individual integers. For example,
trying to read the (3) 32-bit hexadecimal integers deadbeef, 12345678 and
deadc0de when provided as a concatenated string with:
int num;
u32 i, j, k;
num = sscanf("deadbeef12345678deadc0de", "%8x%8x%8x", &i, &j, &k);
will return the number of input items successfully matched and assigned as 3,
the 32-bit integers j and k will have the expected values, but i will be 0.
The libc version of sscanf(), however, will set the value of i to deadbeef.
Should this be expected with the kernel version or is it a bug?
Thanks,
Bruce.
