how to convert a date string to tm_wday in tm structure

Question

Good day all,

I have a date string format say like "2010-03-01" and I want to get the "tm_wday" equivalent of it say like Monday, Tuesday ... Could someone give me a hint on how to achieve this in c. Thank you.

Answer 1

Check the strptime() function:

char *strptime(const char *s, const char *format, struct tm *tm); 

The strptime() function is the converse function to strftime(3) and converts the character string pointed to by s to values which are stored in the tm structure pointed to by tm, using the format specified by format.
