◆ to_int()

template<class T , class TINPUT >

T util::string::to_int ( TINPUT && input )

字符串转整数

Parameters

str 被转换的字符串

Returns: 输出的整数

◆ tolower()

template<class TCH = char>

TCH util::string::tolower ( TCH c )

字符转小写

Parameters

c 字符

Returns: str 如果是大写字符输出响应的小写字符，否则原样返回

Note: 用于替换标准函数里参数是int类型导致的某些编译器warning问题

◆ toupper()

template<class TCH = char>

TCH util::string::toupper ( TCH c )

字符转大写

Parameters

c 字符

Returns: str 如果是小写字符输出响应的大写字符，否则原样返回

		bool	trim_left = `true`,
		bool	trim_right = `true`
	)

移除两边或一边的空白字符

Parameters

str_begin	字符串起始地址
sz	字符串长度，填0则会自动判定长度
trim_left	是否移除左边的空白字符
trim_right	是否移除右边的空白字符

Returns: 返回子串的起始地址和长度

Note: 注意，返回的字符串是源的子串，共享地址。并且不保证以0结尾，需要用返回的长度来判定子串长度
