From the command line:
Code:
time mycopyprog arg1 arg2
real    0m0.03s
user    0m0.01s
sys     0m0.03s

reports the wall clock time, and time in kernel and user mode.

Use a profiler
Code:
cc -p -g mycopyprog.c -o mycopyprog
mycopyprog arg1 arg2
prof mycopyprog
... lines of output

-- with gcc use the same options, but use grpof instead of prof

Or: call gettimeofday before the copy function is called, and then call it again after.
Subtract the two timeval structs to get the time.
man gettimeofday

allegro_exit(3alleg4)						  Allegro manual					     allegro_exit(3alleg4)

NAME
allegro_exit - Closes down the Allegro system. SYNOPSIS
#include <allegro.h> void allegro_exit(); DESCRIPTION
Closes down the Allegro system. This includes returning the system to text mode and removing whatever mouse, keyboard, and timer routines have been installed. You don't normally need to bother making an explicit call to this function, because allegro_init() installs it as an atexit() routine so it will be called automatically when your program exits. Note that after you call this function, other functions like destroy_bitmap() will most likely crash. This is a problem for C++ global destructors, which usually get called after atexit(), so don't put Allegro calls in them. You can write the destructor code in another method which you can manually call before your program exits, avoiding this problem. SEE ALSO
