** 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.
