Functions | |
struct timeval | ast_samp2tv (unsigned int _nsamp, unsigned int _rate) |
Returns a timeval corresponding to the duration of n samples at rate r. Useful to convert samples to timevals, or even milliseconds to timevals in the form ast_samp2tv(milliseconds, 1000) | |
struct timeval | ast_tv (ast_time_t sec, ast_suseconds_t usec) |
Returns a timeval from sec, usec. | |
struct timeval | ast_tvadd (struct timeval a, struct timeval b) |
Returns the sum of two timevals a + b. | |
int | ast_tvcmp (struct timeval _a, struct timeval _b) |
Compres two struct timeval instances returning -1, 0, 1 if the first arg is smaller, equal or greater to the second. | |
int | ast_tvdiff_ms (struct timeval end, struct timeval start) |
Computes the difference (in milliseconds) between two struct timeval instances. | |
int | ast_tvdiff_sec (struct timeval end, struct timeval start) |
Computes the difference (in seconds) between two struct timeval instances. | |
int64_t | ast_tvdiff_us (struct timeval end, struct timeval start) |
Computes the difference (in microseconds) between two struct timeval instances. | |
int | ast_tveq (struct timeval _a, struct timeval _b) |
Returns true if the two struct timeval arguments are equal. | |
struct timeval | ast_tvnow (void) |
Returns current timeval. Meant to replace calls to gettimeofday(). | |
struct timeval | ast_tvsub (struct timeval a, struct timeval b) |
Returns the difference of two timevals a - b. | |
int | ast_tvzero (const struct timeval t) |
Returns true if the argument is 0,0. | |
