char *asctime_r(const struct tm *timeptr); DESCRIPTION Theasctime_r()function converts the broken-down time in the structure pointed to bytimeptrinto a string in the form: Sun Sep 16 01:03:52 1973\n\0 using the equivalent of the following algorithm: ...
On success, asctime() and ctime() return a pointer to a string. On success, asctime_r() and ctime_r() return a pointer to the string pointed to by buf. On success, mktime() returns the calendar time (seconds since the Epoch), expressed as a value of type time_t. On error, ...
