ldap_perror, ld_errno, ldap_result2error, ldap_errlist, ldap_err2string − LDAP protocol error handling routines
#include

struct
ldaperror {
int e_code;
char *e_reason;
};
struct ldaperror ldap_errlist[];
char
*ldap_err2string(err)
int err;

ldap_result2error(ld, res, freeit)
LDAP *ld;
LDAPMessage *res;
int freeit;
These routines provide interpretation of the various error codes returned by the LDAP protocol and LDAP library routines, and assigned to the ld_errno field in the ld structure.
The ldap_result2error() routine takes res, a result as produced by ldap_result(3) or ldap_search_s(3), 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(3) 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(3) works.
The possible values for an ldap error code are:

LDAP_SIZELIMIT_EXCEEDED
An LDAP size limit was exceeded.
|
LDAP_COMPARE_FALSE |
A compare operation returned false. |
|||
|
LDAP_COMPARE_TRUE |
A compare operation returned true. |

The attribute type specified does not exist in the entry.
|
LDAP_UNDEFINED_TYPE |
The attribute type specified is invalid. |
LDAP_INAPPROPRIATE_MATCHING
Filter type not supported for the specified attribute.
LDAP_CONSTRAINT_VIOLATION
An attribute value specified violates some constraint (e.g., a postalAddress has too many lines, or a line that is too long).

|
LDAP_IS_LEAF |
The object specified is a leaf. |
LDAP_ALIAS_DEREF_PROBLEM
A problem was encountered when dereferencing an alias.
LDAP_INAPPROPRIATE_AUTH

|
LDAP_FILTER_ERROR |
An invalid filter was supplied to ldap_search() (e.g., unbalanced parentheses). | ||
