Severity: normal
Dear Maintainer,
In example from man mbstowcs there is an error. If we compile it, we get the
following output:
$ gcc example.c
example.c: In function ‘main’:
example.c:67:21: warning: implicit declaration of function ‘iswalpha’
[-Wimplicit-function-declaration]
if (!iswalpha(*wp))
^~~~~~~~
example.c:72:24: warning: implicit declaration of function ‘iswupper’
[-Wimplicit-function-declaration]
if (iswupper(*wp))
^~~~~~~~
example.c:75:24: warning: implicit declaration of function ‘iswlower’
[-Wimplicit-function-declaration]
if (iswlower(*wp))
^~~~~~~~
Now we add "#include <wctype.h>" to the beginning of this example and the
warning disappears.
But there is another trouble. If we compile with "-Wconversion" gcc option, we
get this output:
$ gcc -Wconversion example.c
example.c: In function ‘main’:
example.c:68:30: warning: conversion to ‘wint_t {aka unsigned int}’ from
‘wchar_t {aka int}’ may change the sign of the result [-Wsign-conversion]
if (!iswalpha(*wp))
