.SH DESCRIPTION
These routines are used to perform LDAP search operations.
-.B ldap_search_s()
+The
+.B ldap_search_ext_s()
+routine
does the search synchronously (i.e., not
-returning until the operation completes).
-.B ldap_search_st()
-does
-the same, but allows a \fItimeout\fP to be specified.
-.B ldap_search()
-is the asynchronous version, initiating the search and returning
-the message id of the operation it initiated.
-\fIBase\fP is the DN of the entry at which to start the search.
-\fIScope\fP is the scope of the search and should be one of LDAP_SCOPE_BASE,
-to search the object itself,
-LDAP_SCOPE_ONELEVEL, to search the object's immediate children,
-or LDAP_SCOPE_SUBTREE, to search the object and all its descendants.
+returning until the operation completes), providing a pointer
+to the resulting LDAP messages at the location pointed to by
+the \fIres\fP parameter.
.LP
-\fIFilter\fP is a string
-
-representation of the filter to apply in the search. Simple filters
-can be specified as \fI(attributetype=attributevalue)\fP. More complex
-filters are specified using a prefix notation according to the following
-BNF:
+The
+.B ldap_search_ext()
+routine is the asynchronous version, initiating the search and returning
+the message id of the operation it initiated in the integer
+pointed to by the \fImsgidp\fP parameter.
.LP
-.nf
- <filter> ::= '(' <filtercomp> ')'
- <filtercomp> ::= <and> | <or> | <not> | <simple>
- <and> ::= '&' <filterlist>
- <or> ::= '|' <filterlist>
- <not> ::= '!' <filter>
- <filterlist> ::= <filter> | <filter> <filterlist>
- <simple> ::= <attributetype> <filtertype> <attributevalue>
- <filtertype> ::= '=' | '~=' | '<=' | '>='
-.fi
+The \fIbase\fP parameter is the DN of the entry at which to start the search.
.LP
-The '~=' construct is used to specify approximate matching. The
-representation for <attributetype> and <attributevalue> are as
-described in RFC 4515. In addition, <attributevalue> can be a single *
-to achieve an attribute existence test, or can contain text and *'s
-interspersed to achieve substring matching.
+The \fIscope\fP parameter is the scope of the search and should be one
+of LDAP_SCOPE_BASE, to search the object itself, LDAP_SCOPE_ONELEVEL,
+to search the object's immediate children, LDAP_SCOPE_SUBTREE, to
+search the object and all its descendants, or LDAP_SCOPE_CHILDREN,
+to search all of the descendants. Note that the latter requires
+the server support the LDAP Subordinates Search Scope extension.
.LP
-For example, the filter "(mail=*)" will find any entries that have a mail
-attribute. The filter "(mail=*@terminator.rs.itd.umich.edu)" will find
-any entries that have a mail attribute ending in the specified string.
-To put parentheses in a filter, escape them with a backslash '\\'
-character. See RFC 4515 for a more complete description of allowable
-filters.
+The \fIfilter\fP is a string representation of the filter to
+apply in the search. The string should conform to the format
+specified in RFC 4515 as extended by RFC 4526. For instance,
+"(cn=Jane Doe)". Note that use of the extension requires the
+server to support the LDAP Absolute True/False Filter extension.
+NULL may be specified to indicate the library should send the
+filter (objectClass=*).
.LP
-\fIAttrs\fP is a null-terminated array of attribute types to return
-from entries that match \fIfilter\fP.
+The \fIattrs\fP parameter is a null-terminated array of attribute
+descriptions to return from matching entries.
If NULL is specified, the return of all user attributes is requested.
-The type "*" (LDAP_ALL_USER_ATTRIBUTES) may be used to request
+The description "*" (LDAP_ALL_USER_ATTRIBUTES) may be used to request
all user attributes to be returned.
-The type "+"(LDAP_ALL_OPERATIONAL_ATTRIBUTES) may be used to request
-all operational attributes to be returned.
-To request no attributes, the type "1.1" (LDAP_NO_ATTRS)
+The description "+"(LDAP_ALL_OPERATIONAL_ATTRIBUTES) may be used to
+request all operational attributes to be returned. Note that this
+requires the server to suppor the LDAP All Operational Attribute
+extension.
+To request no attributes, the description "1.1" (LDAP_NO_ATTRS)
should be listed by itself.
.LP
-\fIAttrsonly\fP should be set to 1 if
-only attribute types are wanted. It should be set to 0 if both
-attributes types and attribute values are wanted.
+The \fIattrsonly\fP parameter should be set to a non-zero value
+if only attribute descriptions are wanted. It should be set to zero (0)
+if both attributes descriptions and attribute values are wanted.
.LP
-.B ldap_search_ext()
-routine allows server and client controls to be specified to extend
-the search request. This routine is asynchronous like
-.BR ldap_search() ,
-but its return value is an LDAP error code. It stores the message id
-of the request in the integer pointed to
-by
-.IR msgidp .
+The \fIserverctrls\fP and \fIclientctrls\fP parameters may be used
+to specify server and client controls, respectively.
.LP
The
.B ldap_search_ext_s()
routine is the synchronous version of
.BR ldap_search_ext().
-It also returns an LDAP error code indicating success or failure
-of the operation.
-.SH ERRORS
-.B ldap_search_s()
-and
-.B ldap_search_st()
-will return the LDAP error code resulting from the search operation.
-See
+.LP
+It also returns a code indicating success or, in the
+case of failure, indicating the nature of the failure
+of the operation. See
.BR ldap_error (3)
for details.
-.B ldap_search()
-returns -1 in case of trouble.
-.LP
-.B ldap_search_s(),
-.B ldap_search_ext_s
-and
-.B ldap_search_st()
-will return the LDAP error code resulting from the search operation.
-See
-.BR ldap_error (3)
-for details.
-.B ldap_search()
-and
-.B ldap_search_ext
-returns -1 in case of trouble.
.SH NOTES
Note that both read
and list functionality are subsumed by these routines,
These routines may dynamically allocate memory. The caller is
responsible for freeing such memory using supplied deallocation
routines. Return values are contained in <ldap.h>.
