41 -n,--progname=NAME Name of the program file to profile
42 -p,--png=FILE Generate PNG graphic and store it in FILE
43 -d,--data=FILE Generate binary data file and store it in FILE
44 -u,--unbuffered Don't buffer output
45 -b,--buffer=SIZE Collect SIZE entries before writing them out
46 --no-timer Don't collect additional information though timer
47 -m,--mmap Also trace mmap & friends
49 -?,--help Print this help and exit
50 --usage Give a short usage message
51 -V,--version Print version information and exit
53 The following options only apply when generating graphical output:
54 -t,--time-based Make graph linear in time
55 -T,--total Also draw graph of total memory use
56 --title=STRING Use STRING as title of the graph
57 -x,--x-size=SIZE Make graphic SIZE pixels wide
58 -y,--y-size=SIZE Make graphic SIZE pixels high
60 Mandatory arguments to long options are also mandatory for any corresponding
61 short options.
