The rmdyjul() function

The rmdyjul() function creates an internal DATE from an array of three short integer values that represent month, day, and year.

Syntax

mint rmdyjul(mdy, jdate)
   int2 mdy[3];
   int4 *jdate;

mdy: An array of short integer values, where mdy[0] is the month (1 - 12), mdy[1] is the day (1 - 31), and mdy[2] is the year (1 - 9999).
jdate: A pointer to a long integer that receives the internal DATE value for the mdy array.

Usage

You can express the year in full form (2007) or abbreviated form (07).

Return codes

0: The operation was successful.
-1204: The mdy[2] variable contains an invalid year.
-1205: The mdy[0] variable contains an invalid month.
-1206: The mdy[1] variable contains an invalid day.

Example

The demo directory contains this sample program in the rmdyjul.ec file.

/*
   * rmdyjul.ec *

   This program converts an array of short integers containing values
   for month, day and year into an integer that stores the date in 
   internal format.

#include <stdio.h>

main()
{
    int4 i_date;
   mint errnum;
    static  short mdy_array[3] = { 12, 21, 2007 };
    char str_date[15];

    printf("RMDYJUL Sample ESQL Program running.\n\n");

    /* Convert MDY array into internal format */
    if ((errnum = rmdyjul(mdy_array, &i_date)) == 0)
      {
      rfmtdate(i_date, "mmm dd yyyy", str_date);
      printf("Date '%s' converted to internal format\n", str_date);
      }
    else
      printf("rmdyjul() call failed with errnum = %d\n", errnum);

    printf("\nRMDYJUL Sample Program over.\n\n");
}

Output
