Suppose I have declared in my C code that the memory model is LARGE, then when initialize the memory pool and allocate memory segment, should I specify the location of the memory segment? In other words, in the following two C code fragments, which one is correct?
#pragma LARGE ... unsigned char xdata *p; init_mempool (&XBYTE [0x2000], 0x400); p = (unsigned char xdata *) malloc (1000);
#pragma LARGE ... unsigned char *p; init_mempool (0x2000, 1024); p = (unsigned char *) malloc (1000);
Look at the description of init_mempool in the Manual - it tells you the types of the parameters.
Rather than the XBYTE macros, I would actually declare an XDATA array and use it as the pool. Take a look at the init_mempool function in the C51 manual. http://www.keil.com/support/man/docs/c51/c51_init_mempool.htm Jon
