WCSWIDTH(3) Linux Programmer's Manual WCSWIDTH(3) NAME wcswidth - determine columns needed for a fixed-size wide-character string SYNOPSIS #define _XOPEN_SOURCE /* See feature_test_macros(7) */ #include <wchar.h> int wcswidth(const wchar_t *s, size_t n); DESCRIPTION The wcswidth() function returns the number of columns needed to repre- sent the wide-character string pointed to by s, but at most n wide characters. If a nonprintable wide character occurs among these char- acters, -1 is returned. RETURN VALUE The wcswidth() function returns the number of column positions for the wide-character string s, truncated to at most length n. ATTRIBUTES Multithreading (see pthreads(7)) The wcswidth() function is thread-safe with exceptions. It can be safely used in multithreaded applications, as long as setlocale(3) is not called to change the locale during its execution. CONFORMING TO POSIX.1-2001. NOTES The behavior of wcswidth() depends on the LC_CTYPE category of the cur- rent locale. SEE ALSO iswprint(3), wcwidth(3) COLOPHON This page is part of release 3.74 of the Linux man-pages project.
