The existing library interfaces do not have a way to do this. Aside from designing and writing your own interface library: no.

Further reading:

  • That interface would have to be in the kernel, or indirectly supported e.g. through permissions, not just in libraries. Library support could be resolved through LD_PRELOAD for just that user. Commented Mar 31, 2016 at 23:44
