// Replacement for strtok() that doesn't use a static to
|
||
|
|
// store the current position. The name comes from the
|
||
|
|
// POSIX threadsafe version of strtok (r = reentrant). The
|
||
|
|
// user provided var lasts is used in place of the static.
|

|

// Yes the Windows version of strtok is already threadsafe,

|
|
// but the fact that you can't call a function that uses strtok()
|
||
|
|
// during a series of strtok() calls is really annoying.
