WCTRANS(3) Linux Programmer's Manual WCTRANS(3) NAME wctrans - wide-character translation mapping SYNOPSIS #include <wctype.h> wctrans_t wctrans(const char *name); DESCRIPTION The wctrans_t type represents a mapping which can map a wide character to another wide character. Its nature is implementation-dependent, but the special value (wctrans_t) 0 denotes an invalid mapping. Nonzero wctrans_t values can be passed to the towctrans(3) function to actually perform the wide-character mapping. The wctrans() function returns a mapping, given by its name. The set of valid names depends on the LC_CTYPE category of the current locale, but the following names are valid in all locales. "tolower" - realizes the tolower(3) mapping "toupper" - realizes the toupper(3) mapping RETURN VALUE The wctrans() function returns a mapping descriptor if the name is valid. Otherwise, it returns (wctrans_t) 0. ATTRIBUTES Multithreading (see pthreads(7)) The wctrans() 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 C99. NOTES The behavior of wctrans() depends on the LC_CTYPE category of the cur- rent locale. SEE ALSO towctrans(3) COLOPHON This page is part of release 3.74 of the Linux man-pages project.
