45 /* Nearly all isa functions require a struct isl_ctx allocated using
46 * isl_ctx_alloc. This ctx contains (or will contain) options that
47 * control the behavior of the library and some caches.
49 * An object allocated within a given ctx should never be used inside
50 * another ctx. Functions for moving objects from one ctx to another
51 * will be added as the need arises.
53 * A given context should only be used inside a single thread.
54 * A global context for synchronization between different threads
55 * as well as functions for moving a context to a different thread
56 * will be added as the need arises.
58 * If anything goes wrong (out of memory, failed assertion), then
59 * the library will currently simply abort. This will be made
60 * configurable in the future.
61 * Users of the library should expect functions that return
62 * a pointer to a structure, to return NULL, indicating failure.
63 * Any function accepting a pointer to a structure will treat
64 * a NULL argument as a failure, resulting in the function freeing
65 * the remaining structures (if any) and returning NULL itself
66 * (in case of pointer return type).
67 * The only exception is the isl_ctx argument, which should never be NULL.
