1. Use the time() function to get the system time value
2. Use localtime() or gmtime() to parse the time value into a tm struct
3. Read the tm_wday member from the structure.

e.g.

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

    int main(void)
    {
        time_t t;
        struct tm* tmLocal;

        time(&t);
        tmLocal = localtime(&t);
        if (tmLocal != NULL)
        {
            printf("It's day number %d (0=Sunday, etc.)\n",
                tmLocal->tm_wday);
        }
        else
        {
            printf("Error computing day number.\n");
            return 1;
        }

        return 0;
    }

You can get further information on these functions from the manual
pages, i.e. type 'man localtime'.

STRUCTURE

[AS225]

Hi all,

I am in the process of moving from UNIX to LINUX.

I have sevral application programs written fortran and
compiled in UNIX environment. Some of the programs
have STRUCTURE. Below is a simple example of it.

      STRUCTURE / RLINE/
         INTEGER     ID
         INTEGER     SEX
         INTEGER     YEAR
      END STRUCTURE
      record /rline/ line(MIN:MAX)

In LINUX I could not compile those programs that
contain STRUCTURE. Can anybody help me how to compile
fortan programs that contain STRUCTRE in LINUX. I want
to compile  it without the chaning it, if it is
possible.


Thanks in advance
AMS

Day Number

[dbisnath]

[-- Attachment #1: Type: text/plain, Size: 294 bytes --]

Hi,
How does one get the day number e.g. Sunday = 0, Monday = 1 etc ?
I want to test the day number against a variable e.g.
if ( dayNumber == DaynumberVar )
  do x,y,z

Thanks
