Functions | |
timeval * | pa_gettimeofday (struct timeval *tv) |
Return the current timestamp, just like UNIX gettimeofday(). | |
pa_usec_t | pa_timeval_diff (const struct timeval *a, const struct timeval *b) PA_GCC_PURE |
Calculate the difference between the two specified timeval structs. | |
int | pa_timeval_cmp (const struct timeval *a, const struct timeval *b) PA_GCC_PURE |
Compare the two timeval structs and return 0 when equal, negative when a < b, positive otherwse. | |
pa_usec_t | pa_timeval_age (const struct timeval *tv) |
Return the time difference between now and the specified timestamp. | |
timeval * | pa_timeval_add (struct timeval *tv, pa_usec_t v) PA_GCC_PURE |
Add the specified time inmicroseconds to the specified timeval structure. | |
timeval * | pa_timeval_store (struct timeval *tv, pa_usec_t v) |
Store the specified uec value in the timeval struct. | |
pa_usec_t | pa_timeval_load (const struct timeval *tv) |
Load the specified tv value and return it in usec. |
