/*
|
|
* The purpose of this header is to enable debug functions.
|
|
* They regroup assert(), DEBUGLOG() and RAWLOG() for run-time,
|
|
* and DEBUG_STATIC_ASSERT() for compile-time.
|
|
*
|
|
* By default, DEBUGLEVEL==0, which means run-time debug is disabled.
|
|
*
|
|
* Level 1 enables assert() only.
|
|
* Starting level 2, traces can be generated and pushed to stderr.
|
|
* The higher the level, the more verbose the traces.
|
|
*
|
|
* It's possible to dynamically adjust level using variable g_debug_level,
|
|
* which is only declared if DEBUGLEVEL>=2,
|
|
* and is a global variable, not multi-thread protected (use with care)
