| @brief Interfaces for getopt() and getopt_long() work-alike functions. | |
| This code was taken from FreeBSD and slightly modified, mostly to rename | |
| symbols with external linkage to avoid naming conflicts in systems where | |
| there are real getopt()/getopt_long() implementations. Changed to use | |
| fixed-width types to allow code using these interfaces to be consistent | |
| with the rest of the product. | |
