[Libguestfs] [PATCH v2 2/4] common/utils: Move libxml2 writer macros to a common header file.
Richard W.M. Jones

Thu Oct 4 12:03:48 UTC 2018
In some places when generating XML output in C code we use some clever
macros:
start_element ("memory") {
attribute ("unit", "MiB");
string ("%d", g->memsize);
} end_element ();
This commit which is mostly refactoring moves the repeated definitions
of these macros into a common header file.
I also took this opportunity to change / clean up the macros:
- The macros are now documented properly.
- comment() and empty_element() macros are now available everywhere.
- Error handling has been made generic.
- Added do..while(0) around some of the macros to make them safe to
use in all contexts.
- Both string() and attribute() take a format string (previously
there were string_format() and attribute_format() variants).
The last point causes the most churn since we must change the callers
to avoid format string security bugs.
