void(* AudioDSPContext::vector_clip_int32)(int32_t *dst, const int32_t *src, int32_t min, int32_t max, unsigned int len)

Clip each element in an array of int32_t to a given minimum and maximum value.

Parameters

dst	destination array constraints: 16-byte aligned
src	source array constraints: 16-byte aligned
min	minimum value constraints: must be in the range [-(1 << 24), 1 << 24]
max	maximum value constraints: must be in the range [-(1 << 24), 1 << 24]
len	number of elements in the array constraints: multiple of 32 greater than zero
