This function determines whether a specified type of access to an array is available, or whether it has been disabled. If access is not available, then any attempt to access the array in this way will fail.

void aryIsacc( Ary $\ast$ary, const char access[ARY__SZACC$+$1], int $\ast$isacc, int $\ast$status )

The valid access types control the following operations on the array:

• ’ BOUNDS’ permits the pixel-index bounds of a base array to be altered.

• ’ DELETE’ permits deletion of the array.

• ’ SHIFT’ permits pixel-index shifts to be applied to a base array.

• ’ TYPE’ permits the data type of the array to be altered.

• ’ WRITE’ permits new values to be written to the array, or the array’ s state to be reset.
