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_meta(3)[1], auth_login_meta(3)[2], auth_getuserinfo_meta(3)[3], and auth_passwd(3)[4].
options is the options field from authinfo (which can be NULL). As described in auth_generic_meta(3)[1] (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.
