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

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

mint rmdyjul(mdy, jdate)

	int2  mdy[3];

	int4  *jdate;

 



mdy

is an array of short integer values, 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). 


jdate

is a pointer to a long integer that receives the internal DATE value for the mdy array. 

You can express the year in full form (1996) or abbreviated form (96).

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