Argp is an interface for parsing unix-style argument vectors.
|
||
|
|
|
||
|
|
Argp provides features unavailable in the more commonly used getopt
|
||
|
|
interface. These features include automatically producing output in
|
||
|
|
response to the `--help' and `--version' options, as described in the
|
||
|
|
GNU coding standards. Using argp makes it less likely that
|
||
|
|
programmers will neglect to implement these additional options or keep
|
||
|
|
them up to date.
|
||
|
|
|
||
|
|
Argp also provides the ability to merge several independently defined
|
||
|
|
option parsers into one, mediating conflicts between them and making
|
||
|
|
the result appear seamless. A library can export an argp option
|
||
|
|
parser that user programs might employ in conjunction with their own
|
||
|
|
option parsers, resulting in less work for the user programs. Some
|
||
|
|
programs may use only argument parsers exported by libraries, thereby
|
||
|
|
achieving consistent and efficient option-parsing for abstractions
|
||
|
|
implemented by the libraries.
|
||
|
|
|
||
|
|
The header file <argp.h> should be included to use argp.
