SLPOpen(3SLP) Service Location Protocol Library Functions SLPOpen(3SLP)NAMESLPOpen - open an SLP handle
SYNOPSIS
cc [ flag... ] file... -lslp [ library... ]
#include <slp.h>
SLPError SLPOpen(const char *pcLang, SLPBoolean isAsync, SLPHandle *phSLP);
DESCRIPTION
The SLPOpen() function returns a SLPHandle handle in the phSLP parame‐
ter for the language locale passed in as the pcLang
parameter. The client indicates if operations on the handle are to
be synchronous or asynchronous through the isAsync parameter. The
handle encapsulates the language locale for SLP requests issued
through the handle, and any other resources required by the
implementation. SLP properties are not encapsulated by the handle,
they are global. The return value of the function is an SLPEr‐
ror code indicating the status of the operation. Upon failure,
the phSLP parameter is NULL.
An SLPHandle can only be used for one SLP API operation at a time. If
the original operation was started asynchronously, any attempt to start
an additional operation on the handle while the original operation is
pending results in the return of an SLP_HANDLE_IN_USE error from the
API function. The SLPClose() function terminates any outstanding
calls on the handle.
PARAMETERS
pcLang A pointer to an array of characters containing the lan‐
guage tag set forth in RFC 1766 for the natural language
locale of requests issued on the handle. This parameter
cannot be NULL.
isAsync An SLPBoolean indicating whether or not the SLPHandle should
be opened for an asynchronous operation.
phSLP A pointer to an SLPHandle in which the open SLPHandle is
returned. If an error occurs, the value upon return is NULL.
ERRORS
This function or its callback may return any SLP error code. See the
ERRORS section in slp_api(3SLP).
EXAMPLES
Example 1 Using SLPOpen()
Use the following example to open a synchronous handle for the German
("de") locale:
SLPHandle HSLP; SLPError err; err = SLPOpen("de", SLP_FALSE, &hSLP)
ENVIRONMENT VARIABLES
SLP_CONF_FILE When set, use this file for configuration.
