[Mesa-dev] [PATCH v4 2/2] egl: add config debug printout (v4)
Silvestrs Timofejevs

Tue Apr 2 15:36:22 UTC 2019
Feature to print out EGL returned configs for debug purposes.
'eglChooseConfig' and 'eglGetConfigs' debug information printout is
enabled when the log level equals '_EGL_DEBUG'. The configs are
printed, and if any of them are "chosen" they are marked with their
index in the chosen configs array.
v2:
a) re-factor the code in line with review comments
b) rename function _snprintfStrcat, split it out and put into the
src/util/u_string.h, make it a separate patch.
v3:
remove unnecessary 'const' qualifiers from the function prototype
v4:
a) re-factor the code in line with review comments
b) move util_strnappend from utils back to eglconfigdebug.c. In my
opinion this function is the best way of achieving the desired
result, so it still used but made private to eglconfigdebug.c.
