The Linux implementation of this interface may differ (consult the corresponding Linux manual page for details of Linux behavior), or the interface may not be implemented on Linux. .\" .SH NAME wcscmp \(em compare two wide-character strings .SH SYNOPSIS .LP .nf #include .P int wcscmp(const wchar_t *\fIws1\fP, const wchar_t *\fIws2\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 \fIwcscmp\fR() function shall compare the wide-character string pointed to by .IR ws1 to the wide-character string pointed to by .IR ws2 . .P The sign of a non-zero return value shall be determined by the sign of the difference between the values of the first pair of wide-character codes that differ in the objects being compared. .SH "RETURN VALUE" Upon completion, \fIwcscmp\fR() shall return an integer greater than, equal to, or less than 0, if the wide-character string pointed to by .IR ws1 is greater than, equal to, or less than the wide-character string pointed to by .IR ws2 , respectively. .SH ERRORS No errors are defined. .LP .IR "The following sections are informative." .SH EXAMPLES None. .SH "APPLICATION USAGE" None. .SH RATIONALE None. .SH "FUTURE DIRECTIONS" None. .SH "SEE ALSO" .IR "\fIwcscasecmp\fR\^(\|)", .IR "\fIwcsncmp\fR\^(\|)" .P The Base Definitions volume of POSIX.1\(hy2017, .IR "\fB\fP" .\" .SH COPYRIGHT Portions of this text are reprinted and reproduced in electronic form from IEEE Std 1003.1-2017, Standard for Information Technology -- Portable Operating System Interface (POSIX), The Open Group Base Specifications Issue 7, 2018 Edition, Copyright (C) 2018 by the Institute of Electrical and Electronics Engineers, Inc and The Open Group.
