This function disables the specified type of access to an array, so that any subsequent attempt to access it in that way will fail. Access restrictions imposed on an array identifier by this routine will be propagated to any new identifiers derived from it, and cannot be revoked.

void aryNoacc( const char $\ast$access, Ary $\ast$ary, int $\ast$status )

Disabling each type of access imposes the following restrictions on an array:

• ’ BOUNDS’ prevents the pixel-index bounds of a base array from being altered.

• ’ DELETE’ prevents the array being deleted.

• ’ MODIFY’ prevents any form of modification to the array (i.e. it disables all the other access types).

• ’ SCALE’ prevents the scale and zero values from being changed.

• ’ SHIFT’ prevents pixel-index shifts from being applied to a base array.

• ’ TYPE’ prevents the data type of the array from being altered.

• ’ WRITE’ prevents new values from being written to the array, or the array’ s state from being reset.
