Subject: tests: have getprocaddress return a return code
X-Git-Tag: 062012170305~17143
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=2caec748ad2361a55d53f98b1d332548e6baf65e;p=profile%2Fivi%2Fmesa.git

tests: have getprocaddress return a return code

These minor changes allow getprocaddress to return an error code
in the case of test failure.  This allows the program to be integrated
into the piglit test suite.
