I can’t seem to find a reference to the syntax of the write command.
In line 120 of gpio.cpp
if (1 != write(fd, &s_values_str[LOW == value ? 0 : 1], 1)) {
To me it looks like fd is the io handle and &s_values_str[LOW == value ? 0 : 1] will be the address of either the “0” or the “1” in the s_values_str array, but what is the last peramiter for (the , 1)? Also why return the address of the string element why not just use a HIGH or LOW? Is this needed for the write function?
I can’t seen to find the write function in the gcc stdio or any of cpp io functions
