/***************************************************************************
* Routines to grab the parameters from the command line:
* All the routines except the main one, starts with GA (Get Arguments) to
* prevent from names conflicts.
* It is assumed in these routine that any pointer, for any type has the
* same length (i.e. length of int pointer is equal to char pointer etc.)
*
* The following routines are available in this module:
* 1. int GAGetArgs(argc, argv, CtrlStr, Variables...)
* where argc, argv as received on entry.
* CtrlStr is the contrl string (see below)
* Variables are all the variables to be set according to CtrlStr.
* Note that all the variables MUST be transfered by address.
* return 0 on correct parsing, otherwise error number (see GetArg.h).
* 2. GAPrintHowTo(CtrlStr)
* Print the control string to stderr, in the correct format needed.
* This feature is very useful in case of error during GetArgs parsing.
* Chars equal to SPACE_CHAR are not printed (regular spaces are NOT
* allowed, and so using SPACE_CHAR you can create space in PrintHowTo).
* 3. GAPrintErrMsg(Error)
* Print the error to stderr, according to Error (usually returned by
* GAGetArgs).
*
* CtrlStr format:
* The control string passed to GetArgs controls the way argv (argc) are
* parsed. Each entry in this string must not have any spaces in it. The
* First Entry is the name of the program which is usually ignored except
* when GAPrintHowTo is called. All the other entries (except the last one
* which we will come back to it later) must have the following format:
* 1. One letter which sets the option letter.
* 2. '!' or '%' to determines if this option is really optional ('%') or
* it must exists ('!')...
* 3. '-' allways.
* 4. Alpha numeric string, usually ignored, but used by GAPrintHowTo to
* print the meaning of this input.
* 5. Sequences starts with '!' or '%'. Again if '!' then this sequence
* must exists (only if its option flag is given of course), and if '%'
* it is optional. Each sequence will continue with one or two
* characters which defines the kind of the input:
* a. d, x, o, u - integer is expected (decimal, hex, octal base or
* unsigned).
* b. D, X, O, U - long integer is expected (same as above).
* c. f - float number is expected.
* d. F - double number is expected.
* e. s - string is expected.
* f. *? - any number of '?' kind (d, x, o, u, D, X, O, U, f, F, s)
* will match this one. If '?' is numeric, it scans until
* none numeric input is given. If '?' is 's' then it scans
* up to the next option or end of argv.
*
* If the last parameter given in the CtrlStr, is not an option (i.e. the
* second char is not in ['!', '%'] and the third one is not '-'), all what
* remained from argv is linked to it.
*
* The variables passed to GAGetArgs (starting from 4th parameter) MUST
* match the order of the CtrlStr:
* For each option, one integer address must be passed. This integer must
* initialized by 0. If that option is given in the command line, it will
* be set to one.
* In addition, the sequences that might follow an option require the
* following parameters to pass:
* 1. d, x, o, u - pointer to integer (int *).
* 2. D, X, O, U - pointer to long (long *).
* 3. f - pointer to float (float *).
* 4. F - pointer to double (double *).
* 5. s - pointer to char (char *). NO allocation is needed!
* 6. *? - TWO variables are passed for each wild request. the first
* one is (address of) integer, and it will return number of
* parameters actually matched this sequence, and the second
* one is a pointer to pointer to ? (? **), and will return an
* address to a block of pointers to ? kind, terminated with
* NULL pointer. NO pre-allocation is needed.
* note that these two variables are pretty like the argv/argc
* pair...
*
* Examples:
*
* "Example1 i%-OneInteger!d s%-Strings!*s j%- k!-Float!f Files"
* Will match: Example1 -i 77 -s String1 String2 String3 -k 88.2 File1 File2
* or match: Example1 -s String1 -k 88.3 -i 999 -j
* but not: Example1 -i 77 78 (option i expects one integer, k must be).
* Note the option k must exists, and that the order of the options is not
* not important. In the first examples File1 & File2 will match the Files
* in the command line.
* A call to GAPrintHowTo with this CtrlStr will print to stderr:
* Example1 [-i OneIngeter] [-s Strings...] [-j] -k Float Files...
*
* Notes:
*
* 1. This module assumes that all the pointers to all kind of data types
* have the same length and format, i.e. sizeof(int *) == sizeof(char *).
