opt_ctx |
On successful return, a pointer to an option context created by mtaOptionStart(). This option context represents the options read from the option file. |

If a value of zero is supplied for len, and there is a non-NULL value for path, the value must be NULL terminated. The length of the file path, not including any NULL terminator, may not exceed ALFA_SIZE bytes. |
len |
Length in bytes, not including any NULL terminator, of the file path. This argument is ignored when a NULL is passed for path. When path is non-NULL and a value of zero is supplied for len, then the file path string must be NULL terminated. |
