** SM_CF_GETOPT -- look up option values in the sendmail.cf file
**
** Open the sendmail.cf file and parse all of the 'O' directives.
** Each time one of the options named in the option vector optv
** is found, store a malloced copy of the option value in optv.
**
** Parameters:
** path -- pathname of sendmail.cf file
** optc -- size of option vector
** optv -- pointer to option vector
**
** Results:
** 0 on success, or an errno value on failure.
** An exception is raised on malloc failure.
