LIST OF FUNCTIONS

Function

Description

iif_get_length_field

Upon entry count points to the first byte of the IIF record, the Record Type. The next 4 bytes are the length field value in LSB-first order. They are read from memory, assembled into the value and returned.

iif_record_type

Tests record_type to see if it is valid. It returns 1 (TRUE) if it is valid, or 0 (FALSE) if the value is not a valid Record Type.

iif_is_eodr

Tests record_type to see if it is the End-of-Data Record Type. It returns 1 (TRUE) if it is, or 0 (FALSE) if it is not the End-of-Data Record Type.
