AUTH_GETOPTION(3) S. Varshavchik. AUTH_GETOPTION(3) 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_meta(3)[1], auth_lo- gin_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 de- scribed in auth_generic_meta(3)[1] (and the others), it is a comma-sepa- rated 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 er- rno 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.
