llu not working in fscanf ??

Asked by Will Smith on 2012-11-01

given text input from file as:

10000,
020,0xf123456abaff123a, ...

while(!feof(pat)){
fscanf(pat," %llu%*[ ,\n]",&conv); // should convert decimal, octal, or hex notation, but this is not the case...chokes on 'x'

using %llx does convert hex, but converts everything else as hex too (which is not the desired behavior).

(some of the *[ ... notation to discard commas and white space may not be optimized)

is this a bug?

If you suspect a bug, you should report one

Assuming your programming in C

Not a bug look here

http://en.wikipedia.org/wiki/Scanf_format_string

%llu is a 64-bit unsigned (assumes input is decimal)

%d is signed int also does not convert

%i is signed int does convert.

Try asking in a C programmers forum

Can you help with this problem?
