function parameter error

Read generated code (directive 'code') and see optimisations to unterstand wich register contains variables and parameters.

Read generated code (directive 'code') and see optimisations to unterstand wich register contains variables and parameters.

I know which registers(registers bank 0) hold these parameter,but still you don't give me the answer how to solve the problem.

For the first problem give me the source of str_cmp().
For the second 'problem' you must note that data at address 0x06 is register R6 in bank 0. The compiler try to put variable in register. In your specific function, it can with a int but it can't with a long.

char str_cmp(const char* str1,const char* str2)
{
int i=0;

if(str1 == NULL || str2 == NULL) return -2;
while(str1[i] != 0 && str2[i] != 0)
{
if(str1[i] == str2[i])i++;
else break;
}
if(str1[i] > str2[i]) return 1;
if(str1[i] < str2[i]) return -1;
return 0;
}

int get_file_entry(const char*filename)
{
xdata char*name; /*for debug convenience*/
int i;

if(filename == NULL) return -1;
i = strlen(filename);
if(i < 1 || i > FILE_NAME_MAX_BYTES) return -1;
i = 0;
while(i < MAX_FILE_COUNT)
{
if(file_allocating_table[i].index != -1)
{
name = file_allocating_table[i].name;
j = str_cmp(name,filename);
if(j == 0)break;
}
i++;
}
return (i < MAX_FILE_COUNT)?i:-1;
}

int play(const char *filename)
{
unsigned int index;
_MALLOC_MEM_ *p_fd = malloc(sizeof(int));

if(p_fd == NULL) return 0; /*no memory*/

*p_fd = get_file_entry(filename);
if(*p_fd == ENOENT) return ENOENT;/* file doesn't exist */

if(sys_op_set.op_count_next_to_curr == (MAX_OPERATION_COUNT - 1)) return 0; //too many operation
/*if there isn't operation in sys_op_set,we should use the current_op for add operation*/

str_cmp is called as follow:
remote()-->create_operation()-->play()-->get_file_entry()-->str_cmp().

Does the internal memory can hold so many parameters?

Is the reason that I don't use the control directive such as NOAREGS or AREGS? But I don't know how to use them.
