Source code is provided (in the \KEIL\C166\LIB folder) for the following library routines:
| Library Routine | Filename | Description |
|---|---|---|
| calloc | calloc.c | Allocates memory for an array of elements. |
| free | free.c | Releases memory allocated with calloc, malloc, or realloc. |
| _getkey | getkey.c | Waits for a character to be received from the serial port. |
| init_mempool | init_mem.c | Initializes the memory pool used by the calloc, free, malloc, and realloc routines. |
| malloc | malloc.c | Allocates a memory block from the memory pool. |
| putchar | putchar.c | Transmits a character using the serial port. |
| realloc | realloc.c | Changes the size of a previously allocated memory block. |
| xcalloc | xcalloc.c | Allocates xhuge memory for an array of elements. |
| xfree | xfree.c | Releases memory allocated with calloc, malloc, or realloc. |
| xinit_mempool | xinitmem.c | Initializes the xhuge memory pool used by the calloc, free, malloc, and realloc routines. |
| xmalloc | xmalloc.c | Allocates a memory block from the xhuge memory pool. |
| xrealloc | xrealloc.c | Changes the size of a previously allocated xhuge memory block. |
You may modify these routines and substitute them for the default routines stored in the library.
An additional source module, traps.c defines trap interrupts for NMI, Stack Overflow, and Stack Underflow.
