This function sets the value of the bad-pixel flag for an array A call to this routine with " bad" set non-zero declares that the specified array may contain bad pixel values for which checks must be made by algorithms which subsequently processes its values. A call with " bad" set to zero declares that there are definitely no bad values present and that subsequent checks for such values may be omitted.

void arySbad( int bad, Ary $\ast$ary, int $\ast$status )

• If the array is mapped for access when this routine is called, then the bad-pixel flag will be associated with the mapped values. This information will only be transferred to the actual data object when the array is unmapped (but only if it was mapped for UPDATE or WRITE access). The value transferred may be modified if conversion errors occur during the unmapping process.
