21 The functionality described on this reference page is aligned with the
22 ISO C standard. Any conflict between the requirements described here
23 and the ISO C standard is unintentional. This volume of POSIX.1‐2008
24 defers to the ISO C standard.
25
26 The wcsrchr() function shall locate the last occurrence of wc in the
27 wide-character string pointed to by ws. The application shall ensure
28 that the value of wc is a character representable as a type wchar_t and
29 a wide-character code corresponding to a valid character in the current
30 locale. The terminating null wide-character code shall be considered to
31 be part of the wide-character string.
32
34 Upon successful completion, wcsrchr() shall return a pointer to the
35 wide-character code or a null pointer if wc does not occur in the wide-
36 character string.
