Description:

The napms() routine delays the calling process for ms milliseconds. This function is similar to delay() and nap().

Note: The suspension time may be greater than the requested amount, due to the nature of time measurement (see the Understanding the Microkernel's Concept of Time chapter of the QNX Neutrino Programmer's Guide), or due to the scheduling of other, higher-priority threads by the system.
