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.
