.SH NAME
OSSL_sleep \- delay execution for a specified number of milliseconds
.SH SYNOPSIS
.IX Header "SYNOPSIS"
.Vb 1
\& #include <openssl/crypto.h>
\&
\& void OSSL_sleep(uint64_t millis);
.Ve
.SH DESCRIPTION
.IX Header "DESCRIPTION"
\&\fBOSSL_sleep()\fR is a convenience function to delay execution of the calling
thread for (at least) \fImillis\fR 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.
.PP
In particular on Windows the maximum amount of time it will sleep is
49 days and on systems where the regular \fBsleep\fR\|(3) is used as the underlying
system call the maximum sleep time is about 136 years.
.SH "RETURN VALUES"
.IX Header "RETURN VALUES"
\&\fBOSSL_sleep()\fR does not return any value.
.SH HISTORY
.IX Header "HISTORY"
\&\fBOSSL_sleep()\fR was added in OpenSSL 3.2.
