This is the popt command line option parsing library. While it is similiar
|
||
|
|
to getopt(3), it contains a number of enhancements, including:
|
||
|
|
|
||
|
|
1) popt is fully reentrant
|
||
|
|
2) popt can parse arbitrary argv[] style arrays while
|
||
|
|
getopt(2) makes this quite difficult
|
||
|
|
3) popt allows users to alias command line arguments
|
||
|
|
4) popt provides convience functions for parsting strings
|
||
|
|
into argv[] style arrays
|
||
|
|
|
||
|
|
popt is used by rpm, the Red Hat install program, and many other Red Hat
|
||
|
|
utilities, all of which provide excellent examples of how to use popt.
|
||
|
|
Complete documentation on popt is available in popt.ps (included in this
|
||
|
|
tarball), which is excerpted with permission from the book "Linux
|
||
|
|
Application Development" by Michael K. Johnson and Erik Troan (availble
|
||
|
|
from Addison Wesley in May, 1998).
