This cannot possibly be true (if what you mean is that they use
ENOMEM[1] from malloc as such an indication). It would make it
impossible to write a correct binding to a normal C library.
Typically C library which calls malloc will do so in the middle of its
execution. Even if the library returns the resulting error up as
a distinguishable error code, you can't just make the same library
call again - it may have done half its work but not the other half.
So I think you must be wrong.
Ian.
[1] NB that when malloc fails there is no -ENOMEM, only ENOMEM.
