| Summary : Space-efficient, typed, external C Arrays (Alpha)
|
Description :
Several XS classes and methods to deal with typed, space-efficient C arrays
are provided. Range checked and tieable.
There are hand-optimized, fast XS versions for the three basic C-types
array of _INT_, _DOUBLE_ and _STRING_ and some sequential aggregate types
int[2][], int[3][], int[4][], double[2][] and double[3][].
This roughly reflects to:
CArray
CIntArray int[]
CInt2Array int[][2]
CInt3Array int[][3]
CInt4Array int[][4]
CDoubleArray double[]
CDouble2Array double[][2]
CDouble3Array double[][3]
CStringArray *char[]
Typed C arrays need about three times less space then untyped perl arrays.
Such as various computional geometry modules dealing with 10.000 - 200.000
double[3]. Modification is done in-place and preferably in bulk.
It might also be easier to write XSUBs by converting the data to CArray\'s
before, pass this pointer to the C func, and handle the results in Perl
then.
The Fetch/Store operations with tied arrays copy the scalars to perl and
back, so it shouldn\'t be abused for BIG data.
Perl\'s safemalloc/safefree is used.
