INFORMIX-ESQL/C Programmer's Manual ESQL/C Function Library

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

mint rjulmdy(jdate, mdy)

	int4  jdate;

	int2  mdy[3];

 



jdate

is the internal representation of the date. 


mdy

is an array of short integers, where mdy[0] is the month (1  to 12), mdy[1] is the day (1 to 31), and mdy[2] is the year (1 to 9999). 

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

/*
