how to remove warning: initialization from incompatible pointer type?

[wanglei0214]

I compiles a program in SLOS, but there is a warning i donot know how
to remove?

here is the framework of the code:
typedef struct device_tree
{
......

union
{
INT8U (*byte)(UID id); //read a byte from a particular device
INT8U (*bit)(UID id); //read a bit from a particular device
INT8U (*block)(UID id, block_data_t *block_w); //read a block
from a particular device
INT8U (*blockext)(UID id, block_data_t *block_w, unsigned long
addr, unsigned long length);
// read a block from flash or cf card
} read;
} device_tree_t;

device_tree_t devices[] =
{
{
/* device driver for serial ports */
"SERIO",
DEVICE_SERIO,
serio_init,
serio_open,
serio_close,
{outbyte},
{inbyte}, //*************this is warning line
*************************
isdataready,
0
},

{
"\0",
0,
0,
0,
0,
{0},
{0},
0,
0
}
};

INT8U inbyte(UID id, block_data_t *block_w)
{
//do something
}

You don't have to post three times!

here is the framework of the code:
typedef struct device_tree
{
......

union
{
INT8U (*byte)(UID id); //read a byte from a particular device
INT8U (*bit)(UID id); //read a bit from a particular device
INT8U (*block)(UID id, block_data_t *block_w); //read a block
from a particular device
INT8U (*blockext)(UID id, block_data_t *block_w, unsigned long
addr, unsigned long length);
// read a block from flash or cf card
} read;
} device_tree_t;

device_tree_t devices[] =
{
{
/* device driver for serial ports */
"SERIO",
DEVICE_SERIO,
serio_init,
serio_open,
serio_close,
{outbyte},
{inbyte}, //*************this is warning line
*************************

Where is inbyte declared?

isdataready,

INT8U inbyte(UID id, block_data_t *block_w)
{
//do something
}

This signature doesn't match the first item in the enum (the only one
you can initialise).

Oops, that should read 'union' not enum.
