| NAME optParseOptions
|
| FUNCTION Parse commandline options.
|
| SYNOPSIS #include "shhopt.h"
| void optParseOptions(int *argc, char *argv[],
| optStruct opt[], int allowNegNum);
|
| INPUT argc Pointer to number of options.
| argv Array of option-/argument-strings.
| opt Array of possible options.
| allowNegNum
| a negative number is not to be taken as
| an option.
|
| OUTPUT argc new argument count.
| argv array with arguments removed.
|
| RETURNS Nothing. Aborts in case of error.
|
| DESCRIPTION This function checks each option in the argv-array
| against strings in the opt-array, and `executes' any
| matching action. Any arguments to the options are
| extracted and stored in the variables or passed to
| functions pointed to by entries in opt.
|
| Options and arguments used are removed from the argv-
| array, and argc is decreased accordingly.
|
| Any error leads to program abortion.
