Functions | |
| void | slot_iterate (void(*callback)(uint8_t slot, void *arg), void *arg) |
MSX For each slot, invoke the given callback with the given arguments. | |

MSX Tests whether a given memory address of the given slot is read-only. | |
| bool | slot_is_MAIN_ROM (uint8_t slot) |
MSX Inspects if the slot is MAIN ROM. | |
| bool | slot_is_SUB_ROM (uint8_t slot) |
MSX Inspects if the slot is SUB ROM. | |
| bool | slot_is_RAM (uint8_t slot) |
MSX Inspects if the slot is RAM. | |

MSX Inspects if the slot is a ROM starting at 0x4000. | |
| bool | slot_is_ROM_p2 (uint8_t slot) |
MSX Inspects if the slot is a ROM starting at 0x8000. | |

Detailed Description
Utility functions to inspect the slot mechanism of MSX.
Example
The following code detects MSX-MUSIC (OPLL) by inspecting each slot.
c
#include <msx.h>
#include <slot.h>
void find_OPLL_callback(uint8_t slot, void * arg) {
uint8_t * p_slot = (uint8_t *)arg;
if (slot_is_internal_OPLL(slot)) {
*p_slot = slot;
}
*p_slot = slot;
}
}
void main(void) {
uint8_t slot = 0;
slot_iterate(find_OPLL_callback, &slot);
if (slot) {
// a MSX-MUSIC (OPLL) found on the slot `slot`.
}
for (;;) {
await_vsync();
}
}
void slot_iterate(void(*callback)(uint8_t slot, void *arg), void *arg)
MSX For each slot, invoke the given callback with the given arguments.
bool slot_is_internal_OPLL(uint8_t slot)
MSX Inspects if the slot is the internal MSX-MUSIC.
Using #include <msx.h> includes almost all C header files in libmsx, for ease to use.
