6 dnl Pass the implementation for a single section as the parameter to
|
|
7 dnl {MASK_}ARRAY_FUNCTION.
|
|
8 dnl The variables base, delta, and len describe the input section.
|
|
9 dnl For masked section the mask is described by mbase and mdelta.
|
|
10 dnl These should not be modified. The result should be stored in *dest.
|

11 dnl The names count, extent, sstride, dstride, base, dest, rank, dim
|
|
12 dnl retarray, array, pdim and mstride should not be used.
|
|
13 dnl The variable n is declared as index_type and may be used.
|
|
14 dnl Other variable declarations may be placed at the start of the code,
|
|
15 dnl The types of the array parameter and the return value are
|
|
16 dnl atype_name and rtype_name respectively.
|
|
17 dnl Execution should be allowed to continue to the end of the block.
|
|
18 dnl You should not return or break from the inner loop of the implementation.
|

19 dnl Care should also be taken to avoid using the names defined in iparm.m4
