NAME

       auth_getoption - Search an option string

SYNOPSIS

	   #include <courierauth.h>

       char *value=auth_getoption(const char *options, const char *keyword);

DESCRIPTION

       This is a convenience function for parsing account options, as received by the callback function invoked by auth_generic(3)[1],
       auth_login(3)[2], auth_getuserinfo(3)[3], and auth_passwd(3)[4].

       options is the options field from authinfo (which can be NULL). As described in auth_generic(3)[1] (and the others), it is a
       comma-separated list of "keyword=value" pairs.

       auth_getoption searches options for a keyword.

RETURNS

       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.
