copyAddrToAddrNonOverlapping# src dest len copies len bytes from src to dest. As the name suggests, these two memory ranges must not overlap, although this pre-condition is not checked. Analogous to the standard C function memcpy, but with a different argument order. Warning: this can fail with an unchecked exception.

copyMutableByteArrayNonOverlapping# src src_ofs dst dst_ofs len copies the range starting at offset src_ofs of length len from the MutableByteArray# src to the MutableByteArray# dst starting at offset dst_ofs. Both arrays must fully contain the specified ranges, but this is not checked. The regions are not allowed to overlap, but this is also not checked. Warning: this can fail with an unchecked exception.

Determine whether a ByteArray# is guaranteed not to move.

Similar to isByteArrayPinned#. Weakly pinned byte arrays are allowed to be copied into compact regions by the user, potentially invalidating the results of earlier calls to byteArrayContents#. See the section `Pinned Byte Arrays` in the user guide for more information. This function also returns true for regular pinned bytearrays.

Determine whether a MutableByteArray# is guaranteed not to move during GC.

isByteArrayWeaklyPinned# but for mutable arrays.

Like newPinnedByteArray# but allow specifying an arbitrary alignment, which must be a power of two. Warning: this can fail with an unchecked exception.

Like newByteArray# but GC guarantees not to move it.

Atomically replace the contents of an IORef, returning the old contents.
