Explain the Spawnlp Functions Used in the NetWare

Spawnlp(flags, execName, arg0,...) 

The Spawnlp function is used to load  a NetWare executable file (NLM) specified by execName  into memory and start execution. Optional  flags may be passed to Spawnlp function to control execution of the spawned NLM. P_NOWAIT clears that the executable is to be loaded and executed   asynchronously to the calling program. Optional arguments (argo,...) may be passed (variable  number) to the invoked program. The  first argument is the name of the executable and the  end of  arguments should be specified with a NULL All arguments are concatenated with white space separating the parameters and can be obtained from standard argc and argv mechanisms or with the function call getcmd( ).
