+.TH LIBSIMPLE_STRCHRNUL 3 2018-11-05 libsimple
+.SH NAME
+libsimple_inchrset, libsimple_inchrcaseset \- the whether a character belongs to a set
+.SH SYNOPSIS
+.nf
+#include <libsimple.h>

+.SH DESCRIPTION
+The
+.BR libsimple_inchrset ()
+and
+.BR libsimple_inchrcaseset ()
+functions scans the string
+.I s
+for an occurence of the character
+.I c
+(it is converted to a
+.BR char ),
+and returns a value indicating whether it exists in the string,
+the scan will always fail if
+.I c
+is the NUL byte.
+.PP
+The comparison is case-sensitive for the
+.BR libsimple_inchrset ()
+function, and case-insensitive for the
+.BR libsimple_inchrcaseset ()
+function.
+.SH RETURN VALUE
+The
+.BR libsimple_inchrset ()
+and
+.BR libsimple_inchrcaseset ()
+functions returns 1 if
+.I c
+is not the NUL byte but can be found in
+.IR s ;
+otherwise 0 is returned.
+.SH ERRORS
+The
+.BR libsimple_inchrset ()
+and
+.BR libsimple_inchrcaseset ()
+functions cannot fail.
+.SH ATTRIBUTES
+For an explanation of the terms used in this section, see
+.BR attributes (7).

+.SH DESCRIPTION
+The
+.BR libsimple_vweprintf ()
+function is a version of the
+.BR printf (3)
+function. It prints the string to the standard error
+(rather than the standard output), and attempts to
+avoid output mangling in case multiple processes are
+writting. Additionally, the output is suffixed with
+.nf
+
+	\fB\(dq %s\en\(dq, \fP<\fIerror message\fP>
+
+.fi
+if
+.I fmt
+ends with a colon
+.RB ( : ),
+otherwise it is suffixed with a <newline> if
+.I fmt
+does not end with a <newline>; otherwise, if
+.I fmt
+is the empty string, the output is suffixed with
+.nf
+
+	\fB\(dq%s\en\(dq, \fP<\fIerror message\fP>
+
+.fi
+Furthermore, if
+.I argv0
+.RB ( "char *" )
+is non-null and
+.I fmt
+does not start with
+.RB \(dq "usage :" \(dq,
+the output is preffixed with
+.nf
