/* An entry for the parser of an options set. The 'os_name' field must point
11
 * to a string, which is treated case-insensitively; the last entry of a table
12
 * must have NULL name. The 'os_type' field must be set to one of the OPT_
13
 * values defined above. The 'os_ptr' field must point to the field that is to
14
 * receive the value of a recognized option. For OPT_STRING, it must point to a
15
 * string of a size set in 'os_val'; the resulting string may be truncated, but
16
 * will always be null-terminated. For OPT_BOOL, it must point to an int which
17
 * will be set to the value in 'os_val' if the option is present. For OPT_INT,
18
 * it must point to an int which will be set to the provided option value;
19
 * 'os_val' is then a base passed to strtol().
