- '0') * multiplier + value; multiplier *= 10; buf++; } while(digit != '\0');
This code reads a sequence of ASCII digits from a buffer and converts them into an unsigned 16-bit integer value.
The variable 'multiplier' is used to keep track of the current place value of the digit being read. For example, when reading "123", the first digit ('1') has a place value of 100, the second digit ('2') has a place value of 10, and the third digit ('3') has a place value of 1. The 'multiplier' variable is initially set to 1, and then multiplied by 10 after each digit is processed to move to the next place value.
The variable 'value' is used to accumulate the integer value of the digits. For each digit, the code subtracts the ASCII code for '0' to get the actual integer value, multiplies it by the current 'multiplier', and adds it to the current 'value'. This updates the 'value' to include the new digit at the appropriate place value.
The code continues reading digits from the buffer until it encounters a null terminator ('\0'), indicating the end of the string. At this point, the final 'value' is the converted integer value of the entire string.
