If you had posted a complete yet minimal, compilable program which reproduces the issue, it is likely that this thread would have been resolved long ago.

jim_mcnamara and don_cragun in posts #2 and #4, respectively, correctly deduced from the nature of the numbers involved that a long long was left-truncated into an integer. However, their responses were handicapped by not having access to a complete program.
Had your original post been more forthcoming, either of them would have seen immediately that the truncation was not caused by a printf bug but by incomplete headers.
You need to include the correct headers so that the compiler doesn't default to implicit function prototypes which treat arguments and return values as integers.
What you are seeing is the result of strtoull's return value taken as an integer before assignment to intValue (as if there were a cast operation there). There are surely other bugs just waiting to bite.
Consult the manual pages of each library function to learn which headers must be included.
Also, you should enable compiler warnings; they would have pointed this out to you.

request_scroll
request_scroll(3alleg4) Allegro manual request_scroll(3alleg4)
NAME
request_scroll - Queues a hardware scroll request with triple buffering. Allegro game programming library.
SYNOPSIS
#include <allegro.h>
int request_scroll(int x, int y);
DESCRIPTION
This function is used for triple buffering. It requests a hardware scroll to the specified position, but returns immediately rather than
waiting for a retrace. The scroll will then take place during the next vertical retrace, but you can carry on running other code in the
meantime and use the poll_scroll() routine to detect when the flip has actually taken place.
Triple buffering is only possible with certain drivers: you can look at the GFX_CAN_TRIPLE_BUFFER bit in the gfx_capabilities flag to see
if it will work with the current driver.
RETURN VALUE
This function returns zero on success, non-zero otherwise.
