=== Constant Table Entry ===
=== Constant Table Entry ===


Each executable's constants are stored as in a constant table. This information is used by ctrulib's SHDR framework to automatically send those values to the GPU when changing to a given program. An entry is constituted by a header and the constant data, the latter of which uses a format specific to the constant type.
