+== Memory allocation ==
+
+As per [wiki:rfc19_safememalloc RFC 19: Safer memory allocation in GDAL],
+you can use VSIMalloc2(x, y) instead of doing CPLMalloc(x * y) or VSIMalloc(x * y).
+VSIMalloc2 will detect potential overflows in the multiplication and return a NULL pointer
+if it happens. This can be useful in GDAL raster drivers where x and y are
+related to the raster dimensions or raster block sizes. Similarly,
+VSIMalloc3(x, y, z) can be used as a replacement for CPLMalloc(x * y * z).
