返回类型：char

参数：

类型参数名称
struct trace_seq *p
const void *buf
intcount
size_tel_size
236  ret等于race_seq_buffer_ptr - return pointer to next location in buffer*@s: trace sequence descriptor* Returns the pointer to the buffer where the next write to* the buffer will happen
237  prefix等于""
238  ptr等于buf
239  buf_len等于count乘el_size
241  trace_seq_putc(p, '{')
243  当ptr小于buf加buf_len循环
245  当:el_size恒等于1
246  Currently only defined when tracing is enabled.
