内核定时机制API之ns_to_timespec64 和 ns_to_timeval,structtimespecns_to_timespec(constsnsec)用于将纳秒转成timespec格式返回给用户其源码分析如下:structtimespecns_to_timespec(constsnsec){structtimesp
其源码分析如下:structtimevalns_to_timeval(consts64 nsec){#首先将形参的纳秒转成timespecstructtimespec ts = ns_to_timespec(nsec);structtimeval tv;#然后通过timespec的结构体成员变量赋值给timeval成员变量.tv.tv_sec = ts.tv_sec; tv.tv_usec = (suseconds_t) ts.tv_nsec /1000;#返回timeval 给用户使...

Since timespec is not year 2038 safe on 32bit system, and we need to convert all timespec variables to timespec64 type for sound subsystem. This patch is used to do preparation for following patches, that will convert all structures defined in uapi/sound/asound.h to use 64-bit time_t....
