If it were djgpp-specific, it is obvious that it goes to 
comp.os.msdos.djgpp, not to comp.lang.c, where compiler-specific 
questions are off-topic.

However, your question has nothing to do with djgpp, but with basic, 
elementary C.

'int *' is not a cast; it's a syntax error.  With a cast, the line
          puts((int *)np);
makes no sense, and the cast is superfluous as well.
Your argument list suggests that np is an array, with the "code" 
suggesting np[0] holds the value you want.  This is probably not true.

int ma(int *np)
{
    printf("This is number of prices? -> %d\n", *np);
    return *np; /* ? */
}


C is really easy if you bother to learn it before coding.
