HP C/iX Library Function Descriptions

asctime

modify the date stored in tm before you print the data. If you only want to print the date,

use the time/ctime combination.

Of all the ctime functions, the localtime function is the most useful. The localtime

function enables you to break up the current time into chunks that can be easily

referenced and examined for such applications as personal calendar programs and

program schedulers. Many of the tm values can be used as indices into arrays containing

strings identifying months and days. For example, declaring an external array like

char *month[]={"January", "February", "March", "April",

"May", "June", "July", "August", "September",

"October", "November", "December"

};

enables you to use tm_mon as an index into this array to obtain the actual month name.

The same thing can be done with tm_wday if you initialize an array containing the names

of the days of the week.
