uwx_self_init_state_cache(3X) uwx_self_init_state_cache(3X)NAMEuwx_self_init_state_cache() - create a cache to improve self-unwind performanceSYNOPSISDESCRIPTIONis part of the Unwind Express Library for Integrity systems; see uwx(3X). creates a cache for quick retrieval of unwind state information when self-unwinding. This routine can be used to improve the performance of programs that perform frequent self-unwind operations. The ideal cache size and associativity will vary for different applications. Experiment with different values and use performance measure- ment tools to determine the best values to use. The memory used by the cache is freed when is called. Parameters info A pointer to the callback info structure created by rows The number of rows in the cache. If this is not a power of two, it will be adjusted to the largest power of two less than the value specified. If the value specified is less than 1, returns without allocating a cache. assoc The associativity of the cache. This determines how many entries with conflicting hash values can be stored in each row of the cache. If the value specified is less than 1, returns without allocating a cache. entsz The size of a cache entry in bytes. The size of the unwind state information stored in a cache entry varies between 64 and 368 bytes. If a stack frame's unwind state is larger than the value specified for entsz, the state will not be saved in the cache. An entry size of 104 is sufficient for most stack frames. If the entsz value is not a multiple of 8 bytes it will be rounded up. If value specified is less than 64 bytes, returns without allocating a cache.RETURN VALUEreturns on success.
