auth_getoption — Search an option string
#include <courierauth.h>
char
*value=auth_getoption( |
const char *options, |
const char *keyword); |
This is a convenience function for parsing account options, as received by the callback function invoked by auth_generic(3), auth_login(3), auth_getuserinfo(3), and auth_passwd(3).
options is the
options field from
authinfo (which can be
NULL). As described in auth_generic(3) (and the
others), it is a comma-separated list of “keyword=value”
pairs.
auth_getoption searches
options for a
keyword.
If options does
not have the keyword,
auth_getoption returns
NULL with errno set to ENOENT. Otherwise auth_getoption allocates a buffer for
value, and returns
it. It is the caller's responsibility to free(3) the returned
buffer.
auth_getoption returns
NULL with errno set to ENOMEM if it cannot allocate a buffer.
