/*****************************************************************
函数名称: AMPS_Trace
功能描述: 跟踪打点函数，在需要记录信息的地方调用此函数即可，通常此函数
使用下面的简化格式:
#define TRACE( nModuleID, nTraceLevel, pMessage , ... ) \
AMPS_Trace( __LINE__, __FILE__, __FUNCTION__, nModuleID,\
nTraceLevel, pMessage, __VA_ARGS__)
入参::
int r_nLineNumber 当前打点所处文件行
char* r_pchFileName 当前打点所处文件名
const char* r_pchFunctionName 当前打点所处函数名
unsigned int r_unModuleId 打点的模块号
unsigned int r_unTraceLevel 跟踪级别
char* r_puchMessage, ... 跟踪内容

返回值:
