1=pod 2 3=head1 NAME 4 5OSSL_sleep - delay execution for a specified number of milliseconds 6 7=head1 SYNOPSIS 8 9 #include <openssl/crypto.h> 10 11 void OSSL_sleep(uint64_t millis); 12 13=head1 DESCRIPTION 14 15OSSL_sleep() is a convenience function to delay execution of the calling 16thread for (at least) I<millis> milliseconds. The delay is not guaranteed; 17it may be affected by system activity, by the time spent processing the call, 18limitation on the underlying system call parameter size or by system timer 19granularity. 20 21In particular on Windows the maximum amount of time it will sleep is 2249 days and on systems where the regular sleep(3) is used as the underlying 23system call the maximum sleep time is about 136 years. 24 25=head1 RETURN VALUES 26 27OSSL_sleep() does not return any value. 28 29=head1 HISTORY 30 31OSSL_sleep() was added in OpenSSL 3.2. 32 33=head1 COPYRIGHT 34 35Copyright 2022-2023 The OpenSSL Project Authors.
