0023 DESCRIPTION
0024 -----------
0025 Function writes the message to current log file. 'lev' is logging level. For function version
0026 log message goes as 'message' parameter. For C/C++ coding it is recommended to
0027 use macro version *TP_LOG*, as it have a format string and it uses more efficient way
0028 to check the logging levels. Macro version have less functions calls during the whole process.
0029
0030 Log levels are following (from ndebug.h):
0031
0032 - log_always 1
0033
0034 - log_error 2
0035
0036 - log_warn 3
0037
0038 - log_info 4
0039
0040 - log_debug 5
