trace_seq_vprintf

函数名称：race_seq_vprintf - sequence printing of trace information*@s: trace sequence descriptor*@fmt: printf format string* The tracer may use either sequence operations or its own* copy to user routines

函数原型：void trace_seq_vprintf(struct trace_seq *s, const char *fmt, va_list args)

返回类型：void

参数：

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

146

save_len等于len

148

如果full则返回

151

race_seq should work with being initialized with 0s.

153

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.

156

如果此条件成立可能性小(为编译器优化)(seq_buf have a buffer that might overflow. When this happens* the len and size are set to be equal.)则

157

len等于save_len

158

full等于1
