+.SH NAME
+strncpy \- copy part of a string
+.SH SYNOPSIS
+.LP
+\fB#include <string.h>
+.br
+.sp
+char *strncpy(char *restrict\fP \fIs1\fP\fB, const char *restrict\fP
+\fIs2\fP\fB, size_t\fP \fIn\fP\fB);
+.br
+\fP
+.SH DESCRIPTION
+.LP
+The \fIstrncpy\fP() function shall copy not more than \fIn\fP bytes
+(bytes that follow a null byte are not copied) from the
+array pointed to by \fIs2\fP to the array pointed to by \fIs1\fP.
+If copying takes place between objects that overlap, the
+behavior is undefined.
+.LP
+If the array pointed to by \fIs2\fP is a string that is shorter than
+\fIn\fP bytes, null bytes shall be appended to the copy
+in the array pointed to by \fIs1\fP, until \fIn\fP bytes in all are
+written.
+.SH RETURN VALUE
+.LP
+The \fIstrncpy\fP() function shall return \fIs1\fP; no return value
+is reserved to indicate an error.
+.SH ERRORS
+.LP
+No errors are defined.
+.LP
+\fIThe following sections are informative.\fP
+.SH EXAMPLES
+.LP
+None.
+.SH APPLICATION USAGE
+.LP
+Character movement is performed differently in different implementations.
+Thus, overlapping moves may yield surprises.
+.LP
+If there is no null byte in the first \fIn\fP bytes of the array pointed
+to by \fIs2\fP, the result is not
+null-terminated.
+.SH RATIONALE
+.LP
+None.
+.SH FUTURE DIRECTIONS
+.LP
+None.
