how to remove warning: initialization from incompatible pointer type?

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}, //*************th is 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}, //*************th is 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.

Hello, It's just a warning, but can anybody explain to me what this warning is: warning C4047: '=' : 'unsigned int ' differs in levels of indirection from 'void *' #include <stdio.h> void swap(int *x, int *y); int main() { int x={1,6}, y={1,10}; printf("Before the function swap, x = %d and y = %d\n\n", x, y);

Hi all. Here is a simple code, which when compiled with gcc results in the warning "incompatible pointer type" for arg 1, as expected. But this is just what I want to do, because it makes it easy for me to handle the single dimensional stream I have as a multidimensional array inside the function func(). Now, I am just wondering if there is a way by which I can disable this incompatible pointer type warning in gcc. Any suggestions?

Hi All, When I compile the following piece of code with gcc, I get 3 "warning: initialization discards qualifiers from pointer target type" messages which refer to the 3 lines marked in the code. What's wrong with these lines? I searched the web for it, but didn't find anything useful. Thanks,
