// This provides a wrapper around system calls which may be interrupted by a
|
|
// signal and return EINTR. See man 7 signal.
|
|
// To prevent long-lasting loops (which would likely be a bug, such as a signal
|
|
// that should be masked) to go unnoticed, there is a limit after which the
|
|
// caller will nonetheless see an EINTR in Debug builds.
|
|
//
|
|
// On Windows and Fuchsia, this wrapper macro does nothing because there are no
|
|
// signals.
|
|
//
|
|
// Don't wrap close calls in HANDLE_EINTR. Use IGNORE_EINTR if the return
|
|
// value of close is significant. See http://crbug.com/269623.
