GW2GetPolicySettings

#include "glasswall.core2.api.h"

int GW2GetPolicySettings (
    Session session,
    char **policiesBuffer,
    size_t *policiesLength,
    Policy_format format);

Parameters

  session The ID of the session as returned by GW2OpenSession

  policiesBuffer A string pointer output parameter which is populated with the policy settings information. The memory used by this pointer does not need to be freed by the user. In the event of a failure this parameter may be set to nullptr.

  policiesLength An output parameter which is populated with the size in bytes of the memory pointed to by `policiesBuffer`

  format The format of the data. This must be `PF_XML`.

Returns

  Returns an integer indicating whether the function call was successful. Negative numbers indicate a failure. See the Return Types table for an explanation of the return codes.

public  int GetPolicySettings(
    int session,
    out IntPtr policiesBufferPtr,
    ref UIntPtr policiesLengthPtr,
    int format)

Returns

Returns an integer GW2_RetStatus enum value. Negative numbers indicate a failure.

Synopsis

import com.glasswall.core2javabridge.*;

public String GW2GetPolicySettingsString(int session, int format) throws GlasswallException

Note:

The GW2GetPolicySettingsString function outputs the currently registered policy settings for the session specified by session.

Please refer to API Overview for Return Types and valid enumerators for format.

This functionality previously required two separate function calls to retrieve the policy setting data. This has now been streamlined to return the settings as a String. The two original functions have been deprecated.

Returns

The GW2GetPolicySettingsString function returns a String containing the policy settings.

A GlasswallException exception will be thrown if session is invalid, or if the policy settings could not be retrieved.

Synopsis - Deprecated Functions

import com.glasswall.core2javabridge.*;

(Deprecated)
public int GW2GetPolicySettings(int session, int format) throws GlasswallException
public byte[] GetPolicyBuffer(int session) throws GlasswallException

Description - Deprecated Functions

The GW2GetPolicySettings function outputs the currently registered policy settings for the session specified by session to the internal policy buffer. Retrieve this data through use of GetPolicyBuffer function. 

Please refer to API Overview for Return Types and valid enumerators for format.

Returns - Deprecated Functions

The GW2GetPolicySettings function returns a GW2_RetStatus enumeration converted to int. The value will be negative if an error occurred. 0 indicates success.

Please refer to API Overview for Return Types and their details.

The GetPolicyBuffer returns a byte[] containing the policy settings. This will be null if GW2GetPolicySettings has not been called.

A GlasswallException exception will be thrown if session is invalid, or if the policy settings could not be retrieved.

Example

const ref = require('ref-napi');

...

function buffer_to_string(buffer, buffer_size) {

    if (!buffer.isNull() && ref.deref(buffer_size) > 0) {
        return Buffer.from(ref.reinterpret(ref.deref(buffer), ref.deref(buffer_size), 0)).toString();
    }
    else {
        return "";
    }
}

...

let policy_file_buffer = ref.alloc(ref.refType(ref.types.CString));
let policy_buffer_size = ref.alloc(ref.types.size_t, 0);

let return_status = gw.GW2GetPolicySettings(session_id, policy_file_buffer, policy_buffer_size, 0);
let xml_string = buffer_to_string(policy_file_buffer, policy_buffer_size);
