(d) Example of low-level interface routines for reentrant library
An example of a low-level interface routine for reentrant library is shown below. This
routine is necessary when using a standard library, which was created by the standard
library generator with the reent option specified.
When an error is returned from the wait_sem function or signal_sem function, set errno as
follows to return from the library function.
When an interrupt with a priority level higher than the current level is generated after
semaphores have been allocated, dead locks will occur if semaphores are allocated again.
Therefore, be careful for processes that share resources because they might be nested by
interrupts.
