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!

Where is inbyte declared?

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

Oops, that should read 'union' not enum.
