SYNOPSIS
#include <slp.h>
SLPError SLPFindSrvs(SLPHandle hSLP, const char *pcServiceType, const
char *pcScopeList, const char *pcSearchFilter, SLPSrvURLCallback *call‐
back, void *pvCookie);
DESCRIPTION
The SLPFindSrvs() function issues a request for SLP services. The query
is for services on a language-specific SLPHandle. It returns the
results through the callback. The parameters will determine the
results.
If an error occurs in starting the operation, one of the SLPError
codes is returned.
PARAMETERS
hSLP The language-specific SLPHandle on which to
search for services. It cannot be NULL.
pcServiceType The service type string for the request. The
pcServiceType can be discovered by a call to
SLPSrvTypes(). Examples of service type strings
include
"service:printer:lpr"
or
"service:nfs"
pcServiceType cannot be NULL.
pcScopeList A pointer to a char containing a comma-sepa‐
rated list of scope names. It cannot be NULL
or an empty string, "".
pcSearchFilter A query formulated of attribute pattern match‐
ing expressions in the form of a LDAPv3 search
filter. See RFC 2254. If this filter is empty,
"", all services of the requested type in the
specified scopes are returned. It cannot be
NULL.
callback A callback through which the results of the
operation are reported. It cannot be NULL.
pvCookie Memory passed to the callback code from the
client. It can be NULL.

srvngst,
NULL);
