seq_buf_vprintf

函数名称：seq_buf_vprintf - sequence printing of information.*@s: seq_buf descriptor*@fmt: printf format string*@args: va_list of arguments from a printf() type function* Writes a vnprintf() format into the sequencce buffer.* Returns zero on success, -1 on overflow.

函数原型：int seq_buf_vprintf(struct seq_buf *s, const char *fmt, va_list args)

返回类型：int

参数：

类型	参数	名称
struct seq_buf *	s
const char *	fmt
va_list	args

WARN_ON(size == 0)

如果len小于size则

len等于vsnprintf - Format a string and place it in a buffer*@buf: The buffer to place the result into*@size: The size of the buffer, including the trailing null space*@fmt: The format string to use*@args: Arguments for the format string* This function generally

如果len加len小于size则

len加等于len

返回:0
