LM3S9B92 I2C not work

please point out the faults, thanks

You didn't explain in what way the code doesn't work, but I'd say it's a fair bet that you don't want the second last semicolon.

As Jack said,

I2CMasterInitExpClk(I2C0_MASTER_BASE, SysCtlClockGet();, true);

Sorry, I typed wrong, not the the second last
semicolon, actually,

this codes is testing on LM3S9B92 Eval board,
the following functions are in a libarry, TI don't
provide the sample code for operating I2C,

SysCtlClockSet(SYSCTL_SYSDIV_1 | SYSCTL_USE_OSC | SYSCTL_OSC_MAIN | SYSCTL_XTAL_16MHZ);
SysCtlPeripheralEnable(SYSCTL_PERIPH_I2C0);
SysCtlPeripheralEnable(SYSCTL_PERIPH_GPIOB);
I2CMasterInitExpClk(I2C0_MASTER_BASE, SysCtlClockGet(), true);
GPIOPinTypeI2C(GPIO_PORTB_BASE, GPIO_PIN_2 | GPIO_PIN_3 );
I2CMasterEnable(I2C0_MASTER_BASE);
while(1)
{ while(I2CMasterBusBusy(I2C0_MASTER_BASE)) ; I2CMasterDataPut(I2C0_MASTER_BASE, 'U');
}

Start posting your code correctly formatted with the pre tags as clearly described just above the message input box.

Then, we will be able to see on the indentation if a while loop is expected to be empty, or if it is expected to control the execution of a following statement.

Right now, your code is unreadable. When posted, it should look like:

#include <stdio.h>

int main(void) {
    printf("Hello world!\n");
    return 0;
}
