int ldap_result2error(LDAP
ld, LDAPMessage
res, int freeit);
struct ldaperror ldap_errlist[];
char
ldap_err2string(int err);
ld_errno
field in the ld structure.
The ldap_result2error routine takes res, a result as
produced by
ldap_result(3ldap)
or
ldap_search_s(3ldap),
and returns the corresponding error code. Possible error codes are listed
below. If the freeit parameter is non-zero it indicates that the
res parameter should be freed by a call to
ldap_msgfree(3ldap)
after the error code has been extracted. The ld_errno
field in
ld is set and returned.
The returned value can be passed to ldap_err2string or looked up in ldap_errlist to get a text description of the message. The string returned from ldap_err2string is a pointer to a static area that should not be modified. The last element in the ldap_errlist array is signaled by an error code of -1.
The ldap_perror routine can be called to print an indication of the error on standard error, similar to the way perror(3C) works.

An attribute type or attribute value specified already exists in the entry.
An invalid attribute value was specified.
The specified object does not exist in the directory.
An alias in the directory points to a nonexistent entry.
A syntactically invalid DN was specified.
