[erlang-questions] Passing a C array to the emulator as an ErlIOVec

[Joel Reymont]

Is there a way to pass a pointer to a C array to the emulator without  
copying?

Can it be wrapped in an ErlIOVec perhaps?

The docs say about ErlIOVec:

"The I/O vector used by the emulator and drivers, is a list of  
binaries, with a SysIOVec pointing to the buffers of the binaries."

Since SysIOVec points to the buffers of the binaries then is there any  
harm in the buffer being the C array in question?

I suppose undocumented functions will need to be used to set up such  
an ErlIOVec but, again,  is there any harm doing it?

	Thanks, Joel
