What does this syntax "success |= MAX35101_Read_2WordValue(TOF_DIFF_AVG_REG, &TOF_DIFF

I am trying to decode the reference code to access the registers in MAX35101 IC.

The code has this syntax at various lines.

What does this mean?

bool MAX35101_Update_TOF_AVG_DIFFData(Flow_ResultsStruct* TOF_DIFF_Results)

{

    bool success = false;
        success |= MAX35101_Read_2WordValue(TOF_DIFF_AVG_REG, &TOF_DIFF_Results->TOF_DiffData);  
    return success;
}

Simply what does Z |= X(a, &b->c); mean?

CodePudding user response：

Z |= X(a, &b->c); could be rewritten as Z = Z | X(a, &(b->c));

We have a pointer to a struct Flow_ResultsStruct* b. To access a member of a struct via a pointer we use a ->. So it is get the address of member c of struct b for which we have a pointer.

Pass a and the address to X.

Now logical or (|) the return value with Z which is false (0) so Z equals the return of the function.
