Indent

indent is a Unix utility that reformats C and C++ code in a user-defined indent style and coding style. Support for C++ code is considered experimental.

It can fix and unify the formating in C file.

indent -o foo.c -gnu -bli0 -hnl -nut -i4 -l130 foo.c

Another better way to use is perhaps this

indent -o %2 -gnu -bli0 -hnl -nut -i4 -l110 -bls -ncs -npcs -nprs -nsaf

 -nsob -lp -cli4 -cbi0 %1

%1 - input file name

%2 - output file name

This indenting works almost perfectly, however it still has a few problems:

1)

do { 

      something; 

} while()

While should be on the same line as the "}". (hint: experiment with do-while cuddling option, maybe it's the right thing)

2) Labels indenting by 2 spaces, so it looks like this:

a = b + 3;

...

MY_LABEL:

free(something); 

return; 

3) Function declarations look a bit wrong:

NTSTATUS
    NTSYSAPI
NtMakeSystemStable()
{ ...
