Definition of data structure to hold time values with nanosecond resolution
#define nstime_add | ( | sum, | |
a | |||

sum += a
#define nstime_subtract | ( | sum, | |

sum -= a
WS_DLL_PUBLIC gboolean filetime_to_nstime | ( | nstime_t * | nstime, |
guint64 | filetime | ||
) |
converts Windows FILETIME to nstime, returns TRUE on success, FALSE on failure
WS_DLL_PUBLIC gboolean nsfiletime_to_nstime | ( | nstime_t * | nstime, |
guint64 | nsfiletime | ||
) |
converts time like Windows FILETIME, but expressed in nanoseconds rather than tenths of microseconds, to nstime, returns TRUE on success, FALSE on failure
compare two times are return a value similar to memcmp() or strcmp().
a > b : > 0 a = b : 0 a < b : < 0
duplicate the current time
a = b
funcion: nstime_copy
a = b
calculate the delta between two times (can be negative!)
delta = b-a
Note that it is acceptable for two or more of the arguments to point at the same structure.
WS_DLL_PUBLIC void nstime_set_unset | ( | nstime_t * | nstime | ) |
set the given nstime_t to (0,maxint) to mark it as "unset" That way we can find the first frame even when a timestamp is zero (fix for bug 1056)
calculate the sum of two times
sum = a+b
Note that it is acceptable for two or more of the arguments to point at the same structure.
WS_DLL_PUBLIC double nstime_to_msec | ( | const nstime_t * | nstime | ) |
converts nstime to double, time base is milli seconds
WS_DLL_PUBLIC double nstime_to_sec | ( | const nstime_t * | nstime | ) |
converts nstime to double, time base is seconds
