@node ispunct
@section @code{ispunct}
@findex ispunct
POSIX specification:@* @url{http://www.opengroup.org/onlinepubs/9699919799/functions/ispunct.html}
Gnulib module: ctype
Portability problems fixed by Gnulib:
@itemize
@item
This function cannot be called from plain inline or extern inline functions
on some platforms:
OS X 10.8.
@end itemize
Portability problems not fixed by Gnulib:
@itemize
@end itemize
Note: This function's behaviour depends on the locale, but does not support
the multibyte characters that occur in strings in locales with
@code{MB_CUR_MAX > 1} (this includes all the common UTF-8 locales).
There are four alternative APIs:
@table @code
@item c_ispunct
This function operates in a locale independent way and returns true only for
ASCII characters. It is provided by the Gnulib module @samp{c-ctype}.
@item iswpunct
This function operates in a locale dependent way, on wide characters. In
order to use it, you first have to convert from multibyte to wide characters,
using the @code{mbrtowc} function. It is provided by the Gnulib module
@samp{wctype}.
@item mb_ispunct
This function operates in a locale dependent way, on multibyte characters.
It is provided by the Gnulib module @samp{mbchar}.
@item uc_is_punct
This function operates in a locale independent way, on Unicode characters.
It is provided by the Gnulib module @samp{unictype/ctype-punct}.
@end table
