AlliedModders - [stocks] String stocks

Here are some string stocks I found useful that I created in sourcepawn. It only works on string type variables

Code:

stock UTIL_StrToLower(String:Source[])
{
    new len = strlen(Source);

    for(new i = 0, b; i < len; i++)
    {
        b = Source[i];

        if(b >= 65 && b <= 90)
        {
            Source[i] += (1<<5);
        }
    }

    return 1;
}

stock UTIL_StrToUpper(String:Source[])
{
    new len = strlen(Source);

    for(new i = 0, b; i < len; i++)
    {
        b = Source[i];

        if(b >= 97 && b <= 122)
        {
            Source[i] -= (1<<5);
        }
    }

    return 1;
}

stock UTIL_IsSpace(ch)
{
    if(ch == 32)
    {
        return 1;
    }

    return 0;
}
