#ifndef NDBMEMCACHE_DEBUG_H
#define NDBMEMCACHE_DEBUG_H
/* DEBUG macros for NDB Memcache.
Debugging is activated by defining DEBUG_OUTPUT at compile-time.
In order to use the THREAD_ variants of these macros, the caller must define
two macros, DEBUG_THD_ID and DEBUG_THD_NAME, in the source file.
DEBUG_THD_ID : (int) numeric thread id
DEBUG_THD_NAME : (const char *) thread name.
DEBUG_INIT(const char * outfile)
Initialize debugging. If outfile is null, STDERR will be used.
DEBUG_ASSERT
An assertion that is compiled only if debugging is enabled.
DEBUG_PRINT(), THREAD_DEBUG_PRINT():
These take printf() style parameter lists.
DEBUG_ENTER(), THREAD_DEBUG_ENTER:
Print the name of the function being entered.
ODD_DEBUG_ENTER(thread_id, thread_name, function_name)
ODD_DEBUG_PRINT(thread_id, thread_name, fmt, ... ):
Manual variants which allow the caller to specify the thread name and id.
