  27 .SH DESCRIPTION
  28 .sp
  29 .LP
  30 The \fBwcscoll()\fR and  \fBwscoll()\fR functions compare the wide character

  31 string pointed to by \fIws1\fR to the wide character string pointed to by
  32 \fIws2\fR, both interpreted as appropriate to the \fBLC_COLLATE\fR category of
  33 the current locale.
  34 .sp
  35 .LP
  36 The \fBwcscoll()\fR and \fBwscoll()\fR functions do not change the setting of
  37 \fBerrno\fR if successful.
  38 .sp
  39 .LP
  40 An application wanting to check for error situations should set \fBerrno\fR to
  41 0 before calling \fBwcscoll()\fR or \fBwscoll()\fR.  If \fBerrno\fR is non-zero
  42 on return, an error has occurred.
  43 .sp
  44 .LP
  45 The function \fBwcsoll_l()\fR behaves identically to \fBwcsoll\fR, except
  46 instead of operating in the current environemtn, it operates in the environment
  47 specified by \fIloc\fR.
  48 .SH RETURN VALUES
  49 .sp
  50 .LP
  51 Upon successful completion, \fBwcscoll()\fR and \fBwscoll()\fR return an
  52 integer greater than, equal to, or less than 0, depending upon whether the wide
  53 character string pointed to by \fIws1\fR is greater than, equal to, or less
  54 than the wide character string pointed to by \fIws2\fR, when both are
  55 interpreted as appropriate to the current locale. On error, \fBwcscoll()\fR and
  56 \fBwscoll()\fR may set \fBerrno\fR, but no return value is reserved to indicate
  57 an error.
  58 .SH ERRORS
  59 .sp
  60 .LP
  61 The \fBwcscoll()\fR and \fBwscoll()\fR functions may fail if:
  62 .sp
  63 .ne 2
  64 .na
  65 \fB\fBEINVAL\fR\fR
  66 .ad

  68 The \fIws1\fR or \fIws2\fR arguments contain wide character codes outside the
  69 domain of the collating sequence.

  30 .LP
  31 The \fBwcscoll()\fR, \fBwcscoll_l()\fR, and \fBwscoll()\fR functions compare
  32 the wide character
  33 string pointed to by \fIws1\fR to the wide character string pointed to by

  35 category.

  37 These  functions do not change the setting of \fBerrno\fR if successful.

  39 An application wanting to check for error situations should set \fBerrno\fR to
  40 0 before calling these functions.  If \fBerrno\fR is non-zero
  41 on return, an error has occurred.

  43 The function \fBwcsoll_l()\fR behaves identically to \fBwcsoll\fR(), except
  44 instead of operating in the current locale, it operates in the locale
  45 specified by \fIloc\fR.
  46 .SH RETURN VALUES

  48 Upon successful completion, these functions return an
  49 integer greater than, equal to, or less than 0, depending upon whether the wide
  50 character string pointed to by \fIws1\fR is greater than, equal to, or less
  51 than the wide character string pointed to by \fIws2\fR, when both are
  52 interpreted as appropriate to the the current locale, or the locale
  53 specified by \fIloc\fR. On error, 
  54 they set \fBerrno\fR, but no return value is reserved to indicate an error.
