error C141: syntax error near 'unsigned'

i checked all the thing's and only after that posted the msg.
This could be a simple typo - eg, missing semicolon or spelling mistake.
there is no such type of mistake

thank's andy
but when i face the problem i done the each and every thing for which i capable but i can not get the way to of it.

here i providing the sample or small model fo the problematic code hope u will help me

unsigned int i,j,k,l,a;
unsigned int sft = 1;




void disp(unsigned int a);

unsigned int go (void);

/*interrupt setting (routine)***/

void TMR_0(void) interrupt 1
     {
     TF0  = 0;
         TR0  = 0;
         TH0  = 0xAA;

     disp(unsigned int);

         TL0  = 0x00;
         TR0  = 1;
     }

void disp(unsigned int a)
     {
     sft = a;

     DECOD1 = 0;        /* 7-segment 1st display */
     DECOD2 = 0;
     DECOD3 = 0;

     P0 = number_code[i];
         if(sft != 1)
           {disp_wait();}
         blink();
     }

     {
         P0   = 0x3f; /* initial  port setting */
         P1   = 0xff;

         P3   = 0xff;

            a = sft;
            return(a);
           }

unnessary code is omited can any one suggest the nessary change in this code.

Where, precisely, does error C141: syntax error near 'unsigned' occur in this code?

/*interrupt setting (routine)***/

void TMR_0(void) interrupt 1
     {
     TF0  = 0;
         TR0  = 0;
         TH0  = 0xAA;

     disp(unsigned int);  at this point

         TL0  = 0x00;
         TR0  = 1;
     }
</prr>

Well, the error should be obvious!

But we've all been at that point of staring at a piece of code for so long that we can no longer see the wood for the trees!

So, back to basics: how do you call a function in 'C'?
How do you supply parameters when you call a fucntion in 'C' - what should go within the parentheses...?

What is the value or variable that you actually want to pass to the display() function at this point...?

unsigned int go()
     {
/***shift key press identification *********/

         if(KEY2_SFT == 0)
           {
           sft++;
           sft_wait();
            KEY2_SFT = 1;
           if(sft > 4)
             {sft = 1;}
            a = sft; i want to pass this value
            return(a);
           }

/*********************************************/

disp(unsigned int);  at this point

OK, let's take this one step at a time.

How do you pass a parameter to a function when you call it?

Insert an appropriate call to my_function in the code below, passing fred as its parameter:

void my_function( unsigned int x ); // function prototype

void main( void )
{
   unsigned int fred;

   // Insert a call here

}

void disp(unsigned int a);
//it going to used in the interrupt

unsigned int go (void);
//going to used in main function


void main()
     {
         P0   = 0x3f; /* initial  port setting */
         P1   = 0xff;
         P2   = 0xf8;
         P3   = 0xff;

         IE   = 0x82;/*timer and interrept setting*/
         TMOD = 0x01;
          TH0  = 0xAA;
           TL0  = 0x00;
         TR0 =  1;

     while(1)
             {
             unsigned int go();
             }
    }

void my_function( unsigned int x ); // function prototype




void main( void )
{
   unsigned int fred;




   my_function(unsigned int);// Inserted a call here




}

OK. you are struggling with the basics of calling a function in 'C'.

You need to set aside your code, and concentrate just on the basic concept of calling a function - any function - and passing a parameter to it.

There is no point in trying to go any further before you have mastered this fundamental concept.

Hint: Look-up "formal" and "actual" parameters in your 'C' textbook.

Then try the exercise again:

Insert an appropriate call to my_function in the code below, passing fred as its parameter:

void my_function( unsigned int x ); // function prototype

void main( void )
{
   unsigned int fred;

   // Insert a call here

}

Insert an appropriate call to my_function in the code below, passing fred as its parameter:

then

void my_function( unsigned int x ); // function prototype
void main( void )
{
unsigned int fred;
my_function(unsigned int fred);// Inserted a call here
}

here the "actual" parameter is fred

and the "formal" parameter is x

Did you compile it?
What did the compiler say?

What does your 'C' text book say about calling functions?
Specifically, what should go inside the brackets?
