liblber ber_printf etc all return -1 for error. On GCC 3.2 (probably less recent versions as well) - compiling several files in libldap produces warnings that comparison is always false, or always true most of these are of the form LBER_ERROR == ber_printf(...) LBER_ERROR is defined as 0xFFFFFFFFUL, and ber_printf returns an int. LBER_ERROR is an unsigned long which is greater then MAX_INT so gcc will always return false, for that case. Suggest LBER_ERROR be redefined as -1
LBER_ERROR is not intended to be a synonym for -1. No code should include a check like this: LBER_ERROR == ber_printf(...) Instead, the code should text against -1, e.g., -1 == ber_printf(...) Note that ber_scanf() does return LBER_ERROR upon error (and a BER tag otherwise). I see problems like you describe in these files: libldap/proxyauthctrl.c libldap/vlistctrl.c Did you see any others? Thanks for reporting this... I love compiler warnings!
ahh okay ... there are others of the form (berrc = ber_printf(...) ) == LBER_ERROR where berrc is an int variable, not always called berrc error.c is the first that comes to mind ( a few != variations as well) a grep for all cases of LBER_ERROR in the libldap directory are almost all incorrect (maybe not all of them now that you mention that scanf returns LBER_ERROR) I can get a list, but not right now.
