in reply to Re^6: sysread/syswrite wrappers
in thread sysread/syswrite wrappers

Yes, they do!

print is just syswrite + a little; readline is just sysread with a loop looking for the current value of $/.

In other words, your wrappers are exactly equivalent to those built-ins; except that they are in C and thus vastly more efficient; and well tried and tested thus more likely to be correct.

As for that; there is a huge difference between quoting the manual and understanding what it says.

The *ONLY REASON* print and readline are said to "not work with select", is because they will block if they receive a partial message, thus preventing the code from getting back to the select. IE. They do exactly what your wrappers do; except they're more likely correct.
