Will it erroneous ??

Hi,
I want to know whether below code will perform expected task or not ?

void test(unsigned char const xdata* buffer);

unsigned char magicString[8] = {0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00};

void main(void) { unsigned char i;

while(1) { for(i=0; i<8; i++) { magicString[i] += 1; } test(magicString); }
}

void test(unsigned char const xdata* buffer) { unsigned char j;

for (j=8; j>0; j++) { send(*buffer++); // another function }
}

Will test() and send() function works ok ? Will send() will send all 8 byte of data of magicString or not ? is there any logic mistake ?

Thanks in advance ?

  • Its hard time for me to understand whats wrong with passing address of magicString i.e. test(&magicString) ?

    "&magicString" is not the address of the first element of the array magicString[]. That's where the error is.

    What you actually want is "&magicString[0]" or just "magicString", which both are a pointer to the first element of magicString.
