+The Linux implementation of this interface may differ (consult

+or the interface may not be implemented on Linux.

+.SH NAME
+memchr
+\(em find byte in memory
+.SH SYNOPSIS
+.LP
+.nf
+#include <string.h>
+.P
+void *memchr(const void *\fIs\fP, int \fIc\fP, size_t \fIn\fP);
+.fi
+.SH 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\(hy2017 defers to the ISO\ C standard.
+.P
+The
+\fImemchr\fR()
+function shall locate the first occurrence of
+.IR c
+(converted to an
+.BR "unsigned char" )
+in the initial
+.IR n
+bytes (each interpreted as
+.BR "unsigned char" )
+pointed to by
+.IR s .
+.P
+Implementations shall behave as if they read the memory byte by byte
+from the beginning of the bytes pointed to by
+.IR s
+and stop at the first occurrence of
+.IR c
+(if it is found in the initial
+.IR n
+bytes).
+.SH "RETURN VALUE"
+The
+\fImemchr\fR()
+function shall return a pointer to the located byte, or a null pointer
+if the byte is not found.
+.SH ERRORS
+No errors are defined.
+.LP
