SLPError SLPFindScopes(SLPHandle hSLP, char** ppcScopes);
The SLPFindScopes() function sets the ppcScopes parameter to a pointer to a comma-separated list including all available scope names. The list of scopes comes from a variety of sources: the configuration file, the net.slp.useScopes
property and the net.slp.DAAddresses property, DHCP, or through the DA discovery process. If there is any order to the scopes, preferred scopes are listed before less desirable scopes. There is always at least one string
in the array, the default scope, DEFAULT.
If no error occurs, SLPFindScopes() returns SLP_OK, otherwise, it returns the appropriate error code.
hSLP The SLPHandle on which to search for scopes. hSLP cannot be NULL.
ppcScopes A pointer to a char pointer into which the buffer pointer is placed upon return. The buffer is null-terminated. The memory should be freed by calling SLPFree(). See SLPFree(3SLP)
This function or its callback may return any SLP error code. See the ERRORS section in slp_api(3SLP).
Example 1: Finding Configured or Discovered Scopes
Use the following example to find configured or discovered scopes:
SLPHandle hSLP; char *ppcScopes; SLPError err; error = SLPFindScopes(hSLP, & ppcScopes);
SLP_CONF_FILE When set, use this file for configuration.
