This conversion is particularly important for cross-development environments.

descriptor, which the translation routines use as follows:
Both the source and destination must have valid buffer pointers.
This member's value specifies the type of
the data to which
points and the type of
data to be created in the destination.
The program supplies a
value in the source;
the library sets the destination's
to the same value.
These values are summarized below.
This member holds the total size, in bytes, of the
memory occupied by the source data and the
size allocated for the destination data.
If the destination buffer is not large enough,
the routines do not change its original contents.
The translation routines reset the destination's
member to the actual size required, after the translation occurs.
The source and destination sizes may differ.
This member holds the version number of the objects (desired) in the buffer.
The source and destination versions are independent.
Translation routines allow the source and destination buffers to coincide.
Other cases where the source and destination buffers overlap
give undefined behavior.
