/*
* This version of the header file corresponds to the profile
* specification version 3.4.
*
* All header file entries are pre-fixed with "ic" to help
* avoid name space collisions. Signatures are pre-fixed with
* icSig.
*
* The structures defined in this header file were created to
* represent a description of an ICC profile on disk. Rather
* than use pointers a technique is used where a single byte array
* was placed at the end of each structure. This allows us in "C"
* to extend the structure by allocating more data than is needed
* to account for variable length structures.
*
* This also ensures that data following is allocated
* contiguously and makes it easier to write and read data from
* the file.
*
* For example to allocate space for a 256 count length UCR
* and BG array, and fill the allocated data. Note strlen + 1
* to remember NULL terminator.
