|
|
|
|
OSSL_sleep - delay execution for a specified number of milliseconds
|
|
|
|
=head1 SYNOPSIS
|
|
|
|
#include <openssl/crypto.h>
|
|
|
|
void OSSL_sleep(uint64_t millis);
|
|
|
|
=head1 DESCRIPTION
|
|
|
|
OSSL_sleep() is a convenience function to delay execution of the calling
|
|
thread for (at least) I<millis> milliseconds. The delay is not guaranteed;
|
|
it may be affected by system activity, by the time spent processing the call,
|
|
limitation on the underlying system call parameter size or by system timer
|
|
granularity.
|
|
|
|
In particular on Windows the maximum amount of time it will sleep is
|
|
49 days and on systems where the regular sleep(3) is used as the underlying
|
|
system call the maximum sleep time is about 136 years.
|
|
|
|
=head1 RETURN VALUES
|
|
|
|
OSSL_sleep() does not return any value.
|
|
|
