+**  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.
