成员函数说明

EnableOutputHtmlFormat()

void BUI::LoggerStorage::EnableOutputHtmlFormat

(

bool

is_html

)

开启Html格式，输出日志。

参数

is_html

true:使用html格式；false：普通文本格式

FileHandler()

FILE * BUI::LoggerStorage::FileHandler

(

)

const

获得文件句柄

(

FILE *

output

)

Initialize the logger as a console logger.

参数

output

If the file pointer is NULL, stdout will be used.

返回

int: Non-zero value upon success or 0 on error

InitFileLogger()

int BUI::LoggerStorage::InitFileLogger	(	const char *	filename,
		long	max_file_size = 1024 *1024 *10,
