int get_date | ( | char * | str, |
struct tm * | date | ||
) |
Reads date from a standard string representation of date.
str | Pointer to string that contains date in one of the formats YYYY-MM-DD, DD/MM/YYYY, DD.MM.YYYY, DD/MM/YY, or DD.MM.YYYY. This string is not modified. |
date | Pointer to allocated struct tm where the date is written |
