43 The \fBldap_compare_s()\fR function is used to perform an LDAP compare
44 operation synchronously. It takes \fIdn\fR, the DN of the entry upon which to
45 perform the compare, and \fIattr\fR and \fIvalue\fR, the attribute type and
46 value to compare to those found in the entry. It returns an LDAP error code,
47 which will be \fBLDAP_COMPARE_TRUE\fR if the entry contains the attribute
48 value and \fBLDAP_COMPARE_FALSE\fR if it does not. Otherwise, some error code
52 The \fBldap_compare()\fR function is used to perform an LDAP compare operation
53 asynchronously. It takes the same parameters as \fBldap_compare_s()\fR, but
54 returns the message id of the request it initiated. The result of the compare
55 can be obtained by a subsequent call to \fBldap_result\fR(3LDAP).
58 The \fBldap_compare_ext()\fR function initiates an asynchronous compare
59 operation and returns \fBLDAP_SUCCESS\fR if the request was successfully sent
60 to the server, or else it returns a LDAP error code if not (see
61 \fBldap_error\fR(3LDAP). If successful, \fBldap_compare_ext()\fR places the
62 message id of the request in \fI*msgidp\fR. A subsequent call to
63 \fBldap_result()\fR, can be used to obtain the result of the add request.
66 The \fBldap_compare_ext_s()\fR function initiates a synchronous compare
67 operation and as such returns the result of the operation itself.
71 \fBldap_compare_s()\fR returns an LDAP error code which can be interpreted by
72 calling one of \fBldap_perror\fR(3LDAP) and friends. \fBldap_compare()\fR
73 returns \fB\(mi1\fR if something went wrong initiating the request. It returns
74 the non-negative message id of the request if it was successful.
78 See \fBattributes\fR(5) for a description of the following attributes:
86 ATTRIBUTE TYPE ATTRIBUTE VALUE
87 Interface Stability Evolving
93 \fBldap\fR(3LDAP), \fBldap_error\fR(3LDAP), \fBattributes\fR(5)
97 There is no way to compare binary values using \fBldap_compare()\fR.
