PROLOG
       This manual page is part of the POSIX Programmer's Manual.  The Linux
       implementation of this interface may differ (consult the corresponding
       Linux manual page for details of Linux behavior), or the interface may
       not be implemented on Linux.


NAME
       memset — set bytes in memory

SYNOPSIS
       #include <string.h>

       void *memset(void *s, int c, size_t n);

DESCRIPTION
       The functionality described on this reference page is aligned with the
       ISO C standard. Any conflict between the requirements described here and
       the ISO C standard is unintentional. This volume of POSIX.1‐2008 defers
       to the ISO C standard.

       The memset() function shall copy c (converted to an unsigned char) into
       each of the first n bytes of the object pointed to by s.

RETURN VALUE
       The memset() function shall return s; no return value is reserved to
       indicate an error.

ERRORS
       No errors are defined.

       The following sections are informative.

EXAMPLES

APPLICATION USAGE
       None.

RATIONALE
       None.

FUTURE DIRECTIONS
