Process Management And Interprocess Communication
=================================================
This chapter describes the NSPR routines that deal with processes. A
process is an instance of a program. NSPR provides routines to create a
new process and to wait for the termination of another process.
NSPR does not provide an equivalent of the Unix ``fork()``. The
newly-created process executes its program from the beginning. A new
process can inherit specified file descriptors from its parent, and the
parent can redirect the standard I/O streams of the child process to
specified file descriptors.
Note that the functions described in this chapter are not available for
MacOS or Win16 operating systems.

Process <#Setting_the_Attributes_of_a_New_Process>`__
- `Creating and Managing
Processes <#Creating_and_Managing_Processes>`__
