\brief vos_trace_msg() - Externally called trace function
Checks the level of severity and accordingly prints the trace messages
\param module - module identifier. A member of the VOS_MODULE_ID
enumeration that identifies the module issuing the trace message.
\param level - trace level. A member of the VOS_TRACE_LEVEL
enumeration indicating the severity of the condition causing the
trace message to be issued. More severe conditions are more
likely to be logged.
\param strFormat - format string. The message to be logged. This format
string contains printf-like replacement parameters, which follow
this parameter in the variable argument list.
\return nothing
