The mi_put_datetime() function
The mi_put_datetime() function copies an mi_datetime (DATETIME) value, converting any difference in alignment or byte order on the server computer to that of the client computer.
Syntax
mi_unsigned_char1 *mi_put_datetime(data_ptr, dtime_ptr)
mi_unsigned_char1 *data_ptr;
mi_datetime *dtime_ptr;- data_ptr
- A pointer to the buffer to which to copy the mi_datetime value.
- dtime_ptr
- A pointer to the buffer from which to copy the mi_datetime value.

Usage
The mi_put_datetime() function copies the mi_datetime value from the buffer that dtime_ptr references into the user-defined buffer that data_ptr references. Upon completion, mi_put_datetime() returns the address of the next position to which data can be copied in the data_ptr buffer. The function returns the data_ptr address advanced by nbytes bytes, ready for copying in the next value. In other words, if n is the length of the value that dtime_ptr identifies, the returned address is n bytes advanced from the original buffer address in data_ptr.
The mi_put_datetime() function is useful in a send support function of an opaque data type that contains an mi_datetime value. Use this function to send an mi_datetime field of an opaque-type internal structure to a client application (which possibly has unaligned data buffers).
For more information about the use of mi_put_datetime() in a send support function, see the HCL OneDB™ DataBlade® API Programmer's Guide.
Return values
- An mi_unsigned_char1 pointer
- The new address in the data_ptr data buffer.
- NULL
- The function was not successful.
