part of the official libcurl API http://curl.haxx.se/lxr/source/lib/README.curlx The documented way of using them would be to use timeval.c as a source code file. The above described method works very well when statically linking libcurl and apps, test programs, but has several drawbacks when you build a true shared libcurl (i.e. Name space clash at linkage stage as functions are defined more than once. Windows makefiles are not capable of handling this system of source-level sharing) So... Now testutil.h and testutil.c define and implement tutil_tvnow and tutil_tvdiff which replace curlx_tvnow and curlx_tvdiff for the libtest programs. Doing this we avoid the above described problems, and the code in the testsuite does not impose the need to keep those functions public in libcurl even when not part of the API.
