C getdate() Function

The getdate() function is defined in the time.h header file. This function helps to converts the given date/time specifications pointed to by string into a structure 'tm' or into a broken-down time.

struct tm *getdate(const char *string); #where string is representation of a date or time

getdate() Parameters: 

The getdate() function takes a single parameter as a pointer string which has the representation of date/time. The structure tm is allocated in static storage, and it will be overwritten by further getdate() function calls.
       

getdate() Return Value

The function converts the string representation of date/time into broken-down time and is stored in a tm structure. And the pointer to this structure is returned as the function output. To return error values this function uses an external variable or macro getdate_err.

Examples of getdate() 

#include <stdio.h>
#include <time.h>

int main()
{
   struct date datm;
  
  
    getdate(&datm;);
  
    printf("Current system's date:\n");
    printf("%d/%d/%d",
           datm.da_day,
           datm.da_mon,
           datm.da_year);
  
    return 0;
}

Output:

Current system's date:
18/4/2019

#include <stdio.h>
#include <time.h>

int main (){

    struct date dt;
 
   getdate(&dt;);
 
   printf("Operating system's current date is %d-%d-%d\n"
   ,dt.da_day,dt.da_mon,dt.da_year);
 
   return 0;
}

Output:

Operating system’s current date is 12-01-2012
