+.TH LIBSIMPLE_STRNCASECMPNUL 3 2018-10-23 libsimple
+.SH NAME
+libsimple_strncasecmpnul \- compare two strings
+.SH SYNOPSIS
+.nf
+#include <libsimple.h>
+
+static inline int libsimple_strncasecmpnul(const char *\fIa\fP, const char *\fIb\fP, size_t \fIn\fP);

+#ifndef strncasecmpnul

+.IR \-lsimple .
+.SH DESCRIPTION
+The
+.BR libsimple_strncasecmpnul ()
+function compares the strings
+.IR a ,
+truncated to
+.I n
+bytes unless it is shorter,
+and
+.IR b ,
+truncated to
+.I n
+bytes unless it is shorter,
+both of which may be
+.BR NULL ,
+which is treated as less than the empty string.
+.PP
+If one of the strings begins with the other string
+but is longer, the longer string is treated as
+greater than the shorter string.
+.PP
+The comparison is case-insensitive and made as
+if the strings were converted to lowercase and as
+.IR "unsigned char *" s.
+.SH RETURN VALUE
+The
+.BR libsimple_strncasecmpnul ()
+function returns a negative value if
+.I a
+is less than
+.IR b ,
+a positive value if
+.I a
+is greater than
+.IR b ,
+and 0 otherwise.
+.SH ERRORS
+The
+.BR libsimple_strncasecmpnul ()
+function cannot fail.
+.SH ATTRIBUTES
+For an explanation of the terms used in this section, see
