WCSNLEN(3) Linux Programmer's Manual WCSNLEN(3)NAMEwcsnlen - determine the length of a fixed-size wide-character stringSYNOPSIS#define _GNU_SOURCE #include <wchar.h> size_t wcsnlen(const wchar_t *s, size_t maxlen);DESCRIPTIONThe wcsnlen() function is the wide-character equivalent of the strnlen(3) function. It returns the number of wide-characters in the string pointed to by s, not including the terminating L' ' character, but at most maxlen. In doing this, wcsnlen() looks only at the first maxlen wide-characters at s and never beyond s+maxlen.RETURN VALUEThe wcsnlen() function returns wcslen(s), if that is less than maxlen, or maxlen if there is no L' ' character among the first maxlen wide characters pointed to by s.CONFORMING TOThis function is a GNU extension.SEE ALSOstrnlen(3), wcslen(3)COLOPHONThis page is part of release 3.25 of the Linux man-pages project.
