| .SH NAME |
| getutmp, getutmpx \- copy utmp structure to utmpx, and vice versa |
| .SH SYNOPSIS |
| .nf |
| .BR "#define _GNU_SOURCE" " /* See feature_test_macros(7) */" |
| .B #include <utmpx.h> |
| .PP |
| .BI " void getutmp(const struct utmpx *" ux ", struct utmp *" u ); |
| .BI " void getutmpx(const struct utmp *" u ", struct utmpx *" ux ); |
| .fi |
| .SH DESCRIPTION |
| The |
| .BR getutmp () |
| function copies the fields of the |
| .I utmpx |
| structure pointed to by |
| .I ux |
| to the corresponding fields of the |
| .I utmp |
| structure pointed to by |
| .IR u . |
| The |
| .BR getutmpx () |
| function performs the converse operation. |
| .SH RETURN VALUE |
| These functions do not return a value. |
| .SH VERSIONS |
| These functions first appeared in glibc in version 2.1.1. |

| .SH CONFORMING TO |
| These functions are nonstandard, but appear on a few other systems, |
| such as Solaris and NetBSD. |
| .SH NOTES |
| These functions exist primarily for compatibility with other |
| systems where the |
| .I utmp |
| and |
| .I utmpx |
| structures contain different fields, |
| or the size of corresponding fields differs. |
| .\" e.g., on Solaris, the utmpx structure is rather larger than utmp. |
| On Linux, the two structures contain the same fields, |
| and the fields have the same sizes. |
