The CodingStyle for libvirt-cim (and libcmpiutil) is mostly kernel
style, but with the following "clarifications":

- Eight-space indents

- No single-line if statements.  This means none of this:

    if (foo) bar;

- Keywords and parens separated by one space (i.e. "if (" not "if(")

- 80-char width limit.  Break long function calls by putting *every*
  parameter of the call on its own line.  There are a few exceptions
  to the "every parameter" rule, such as for cu_statusf() calls.
  Unless you've seen another example in the code, put each parameter
  on a line.

- Identifiers should be named with underbars_and_lowercase.  The
  libvirt style is to use CamelCase, but try to limit that to
  operations directly related to libvirt and don't spread it to the
  rest of the code.

- Macros should be ALL_UPPERCASE

- Braces around blocks should look like this:

  if (foo) {
    . . .
  } else if (bar) {
    . . .
  } else {
    . . .
  }

- Absolutely all files should contain the following block at the end:

  /*
   * Local Variables:
   * mode: C
   * c-set-style: "K&R"
   * tab-width: 8
   * c-basic-offset: 8
   * indent-tabs-mode: nil
   * End:
   */

  This ensures that emacs folks will have the style correct (they're
  already halfway there by their choice in editor anyway).

- Pointer and integer comparisons should be against something
  concrete.  The only time the following style should be used is if
  foo is a bool:

    if (!foo) /* ONLY if foo is a bool */
      bar;

  For pointers and integers, do this:

    if (foo == NULL) /* if foo is a pointer */
      bar;

    if (foo == -1) /* if foo is an integer */
      bar;
