--EXPECTF--
Write some data to the file:
array(9) {
["wrapper_type"]=>
string(9) "plainfile"
["stream_type"]=>
string(5) "STDIO"
["mode"]=>
string(2) "w+"
["unread_bytes"]=>
int(0)
["seekable"]=>
bool(true)
["uri"]=>
string(%i) "%s.tmp"
["timed_out"]=>
bool(false)
["blocked"]=>
bool(true)
["eof"]=>
bool(false)
}
Read a line of the file, causing data to be buffered:
string(15) "a line of data
"
array(9) {
["wrapper_type"]=>
string(9) "plainfile"
["stream_type"]=>
string(5) "STDIO"
["mode"]=>
string(2) "w+"
["unread_bytes"]=>
int(285)
["seekable"]=>
bool(true)
["uri"]=>
string(%i) "%s.tmp"
["timed_out"]=>
bool(false)
["blocked"]=>
bool(true)
["eof"]=>
bool(false)
}
Read 20 bytes from the file:
array(9) {
["wrapper_type"]=>
string(9) "plainfile"
["stream_type"]=>
string(5) "STDIO"
["mode"]=>
string(2) "w+"
["unread_bytes"]=>
int(265)
["seekable"]=>
bool(true)
["uri"]=>
string(%i) "%s.tmp"
["timed_out"]=>
bool(false)
["blocked"]=>
bool(true)
["eof"]=>
bool(false)
}
Read entire file:
array(9) {
["wrapper_type"]=>
string(9) "plainfile"
["stream_type"]=>
string(5) "STDIO"
["mode"]=>
string(2) "w+"
["unread_bytes"]=>
int(0)
["seekable"]=>
bool(true)
["uri"]=>
string(%i) "%s.tmp"
["timed_out"]=>
bool(false)
["blocked"]=>
bool(true)
["eof"]=>
bool(true)
