| Function | getargs |
| Include file | GETARGS.H |
| Prototype | int getargs( int argc , char **argv , ARG *tbl_ptr , int tbl_size ) |
| Remarks | Process command line arguments. Stripping all command line switches out of argv. Return a new argc. If an error is found local_exit(1) is called (getargs won't return) and a usage message is printed showing all arguments in the table. |
| Function | stoi |
| Include file | GETARGS.H |
| Prototype | static int stoi( register char **instr ) |
| Remarks | stoi is a more powerful version of atoi. Convert string to integer. If string starts with 0x it is interpreted as a hex number, else if it starts with a 0 it is octal, else it is decimal. Conversion stops on encountering the first character which is not a digit in the indicated radix. *instr is updated to point past the end of the number |
| Function | setarg |
| Include file | GETARGS.H |
| Prototype | static char *setarg( ARG *argp , char *linep ) |
| Remarks | Set an argument , argp points at the argument table entry corresponding to *linep. Return linep , updated to point past the argument being set. |
| Function | findarg |
| Include file | GETARGS.H |
| Prototype | static ARG *findarg( int c , ARG *tbl_ptr , int tbl_size ) |
| Remarks | Return pointer to argument table entry corresponding to c ( or 0 if c isn't in the table ). |
| Function | pr_usage |
| Include file | GETARGS.H |
| Prototype | static void pr_usage( ARG *tbl_ptr , int tbl_size , char *arg_ptr ) |
| Remarks | Print the arg_tbl in the form:
