KHTTP_EPOCH2TMS(3) Library Functions Manual KHTTP_EPOCH2TMS(3) NAME KHTTP_EPOCH2TM, khttp_epoch2tms -- convert time to components LIBRARY library "libkcgi" SYNOPSIS #include <sys/types.h> #include <stdarg.h> #include <stdint.h> #include <kcgi.h> int khttp_epoch2tms(int64_t epoch, int *tm_sec, int *tm_min, int *tm_hour, int *tm_mday, int *tm_mon, int *tm_year, int *tm_wday, int *tm_yday); int KHTTP_EPOCH2TM(int64_t epoch, struct tm *tm); DESCRIPTION Format an epoch value (seconds since Jan 1, 1970, 00:00:00 UTC) into its broken-down time components suitable for struct tm operations. The components of khttp_epoch2tms() are filled in as follows: tm_sec seconds 0-59 tm_min minutes 0-59 tm_hour hours 0-23 tm_day day of month 1-31 tm_mon month 0-11 tm_year year minus 1900 tm_yday day in year 0-365 tm_wday day in week 0-6 (Sunday = 0) If any of the pointers are NULL, they are ignored. The KHTTP_EPOCH2TM() macro fills in tm with the above values. Other fields in the struct tm structure, like tm_gmtoff, are not touched. These deprecate the original kutil_epoch2tmvals() function and KUTIL_EPOCH2TM() macro, both of which had undefined behaviour in some corner cases. For conversion without possible overflow or underflow, use khttp_epoch2datetime(3). RETURN VALUES These return zero on failure and non-zero on success. Failure occurs if epoch will overflow or underflow tm_year, which occurs around the year +-6.7+16.
