   7 .TH TOUPPER 3C "Jun 21, 2014"
   8 .SH NAME
   9 toupper, toupper_l \- transliterate lower-case characters to upper-case
  10 .SH SYNOPSIS
  11 .LP
  12 .nf
  13 #include <ctype.h>
  14 
  15 \fBint\fR \fBtoupper\fR(\fBint\fR \fIc\fR);
  16 .fi
  17 .LP
  18 .nf
  19 \fBint\fR \fBtoupper_l\fR(\fBint\fR \fIc\fR, \fBlocale_t\fR \fIloc\fR);

  22 .SH DESCRIPTION
  23 .LP
  24 The \fBtoupper()\fR function has as a domain a type \fBint\fR, the value of
  25 which is representable as an \fBunsigned char\fR or the value of \fBEOF\fR. If
  26 the argument has any other value, the argument is returned unchanged. If the
  27 argument of \fBtoupper()\fR represents a lower-case letter, and there exists a
  28 corresponding upper-case letter (as defined by character type information in
  29 the locale category \fBLC_CTYPE\fR),   the result is the corresponding
  30 upper-case letter. All other arguments in the domain are returned unchanged.
  31 .LP
  32 The function \fBtoupper_l()\fR behaves identically to \fBtoupper()\fR, except
  33 instead of operating in the current locale, it operates in the locale
  34 specified by \fIloc\fR.
  35 .SH RETURN VALUES
  36 .LP
  37 On successful completion, \fBtoupper()\fR returns the upper-case letter
  38 corresponding to the argument passed.
  39 .SH ERRORS
  40 .LP
  41 No errors are defined.
