Description
newlib uses the wait() function to wait for all child processes to exit. Because the HAL does not support
spawning child processes, this function returns immediately.
Return
On return, the content of status is set to zero, which indicates there is no child processes.
The return value is always –1 and errno is set to ECHILD, which indicates that there are no child processes
to wait for.
