* getopt()
|
|
||||||
*
|
|
||||||
* The getopt() function is a command line parser. It returns the next
|
|
||||||
* option character in argv that matches an option character in opstring.
|
|
||||||
*
|
|
||||||
* The argv argument points to an array of argc+1 elements containing argc
|
|
||||||
* pointers to character strings followed by a null pointer.
|
|
||||||
*
|
|
||||||
* The opstring argument points to a string of option characters; if an
|
|
||||||
* option character is followed by a colon, the option is expected to have
|
|
||||||
* an argument that may or may not be separated from it by white space.
|
|
||||||
* The external variable optarg is set to point to the start of the option
|
|
||||||
* argument on return from getopt().
|
|
||||||
*
|
|
||||||
* The getopt() function places in optind the argv index of the next argument
|
|
||||||
* to be processed. The system initializes the external variable optind to
|
|
||||||
* 1 before the first call to getopt().
|
|
||||||
*
|
|
||||||
* When all options have been processed (that is, up to the first nonoption
|
|
||||||
* argument), getopt() returns EOF. The special option "--" may be used to
|
|
||||||
* delimit the end of the options; EOF will be returned, and "--" will be
|
|
||||||
* skipped.
|
|
||||||
*
|
|
||||||
* The getopt() function returns a question mark (?) when it encounters an
|
|
||||||
* option character not included in opstring. This error message can be
|
|
||||||
* disabled by setting opterr to zero. Otherwise, it returns the option
|
|
||||||
* character that was detected.
|
|
||||||
*
|
|
||||||
* If the special option "--" is detected, or all options have been
|
|
||||||
* processed, EOF is returned.
|
|
||||||
*
|
|
||||||
* Options are marked by either a minus sign (-) or a slash (/).
|
|
||||||
*
|
|
||||||
* No errors are defined.
