Hey, I am learning how to create natives and after reading the article on wiki I came up with this. Does it seem correct? At least it works but it doesn't necessarily mean that's it's 'smartly' done.

.inc file

Code:
/**
 * Check if a client has a certain admin flag.
 *
 * @param num1    a client.
 * @param num2    a flag.
 * @return        True if the client has the flag, false otherwise.
 */
 
 native bool CheckClientFlag(int client, char[] flag);
.sp file

Code:
public APLRes AskPluginLoad2(Handle myself, bool late, char[] error, int err_max)
{
	CreateNative("CheckClientFlag", Native_FlagHelper);
	return APLRes_Success;
}

public any Native_FlagHelper(Handle plugin, int numParams)
{
	int client = GetNativeCell(1);
	char flag = view_as<int>(GetNativeCell(2));
	return(CheckCommandAccess(client, "", flag, true));
}
example

Code:
CheckClientFlag(client, "b");

And yes, I know that a native like that doesn't make much sense but it's just an example.

PHP Code:
public any Native_FlagHelper(Handle pluginint numParams)
{
    
int client GetNativeCell(1);
    
char flag[5];
        
GetNativeString(2flag5);
    return(
CheckCommandAccess(client""ReadFlagString(flag), true));

Rest seem correct to me

FYI, it isn't safe (or sane) to pass an empty command string to CheckCommandAccess.

Why is that? Especially if one doesn't have a need to check overrides or commands.

You can directly check if they have a certain flag through GetUserAdmin and checking if they have access to a certain flag.
