/* I don't recommend using this interface in general. Use `free'.

[49] Fix | Delete

[50] Fix | Delete

* I'm told Microsoft Windows may use one set of `malloc' and `free'

[51] Fix | Delete

* in a library, and another incompatible set in a statically compiled

[52] Fix | Delete

* application that link to the library, thus creating problems if the

[53] Fix | Delete

* application would invoke `free' on a pointer pointing to memory

[54] Fix | Delete

* allocated by the library. This motivated adding this function.

[55] Fix | Delete

[56] Fix | Delete

* The theory of isolating all memory allocations and de-allocations

[57] Fix | Delete

* within a code package (library) sounds good, to simplify hunting

[58] Fix | Delete

* down memory allocation related problems, but I'm not sure if it is

[59] Fix | Delete

* worth enough to motivate recommending this interface over calling

[60] Fix | Delete

* `free' directly, though.

[61] Fix | Delete

[62] Fix | Delete

* See the manual section 'Memory handling under Windows' for more

[63] Fix | Delete

* information.
