Compare strings - file functions - GranaT3 - 02.12.2015

I want to know how many "GranaT3" I have in my file "name.txt"

Код:

new File:handle = fopen("name.txt", io_read), buf[128];
 
	if(handle)
	{
		while(fread(handle, buf))
		{
                     if(!strcmp(buf, "GranaT3", true))
                     {
                     printf("%s", buf);
                     }
		}  			
	}

	else
	{
		print("The file \"file.txt\" does not exists, or can't be opened.");
	}

But nothing prints (code does not work). What would be the right way ?.

Re: Compare strings - file functions - CmZxC - 02.12.2015

You're using "while" incorrectly.

PHP код:



while(fread(handle, buf))
{
            if(!strcmp(buf, "GranaT3", true))
            {
                printf("%s", buf);
            }
}

}

No, that's not the problem, I tested this and it's the same result (none).

Re: Compare strings - file functions - CmZxC - 02.12.2015

Where did you even paste your code? Is it even being called?

If not, place it in either main() or OnGameModeInit.

It is a function.

The function is called in:

pawn Код:

public OnGameModeInit()
{
    file_a();

    return 1;
}

That's not the problem.
