@item
|
|
This function does not support the error values that are specified by POSIX
|
|
but not defined by the system, on some platforms:
|
|
OpenBSD 4.0, OSF/1 5.1, NonStop Kernel, Cygwin 1.5.x, mingw, MSVC 9.
|
|
@item
|
|
This function reports failure for @code{strerror(0)} (by setting
|
|
@code{errno} or using a string similar to out-of-range values),
|
|
although POSIX requires this to leave @code{errno} unchanged and
|
|
report success, on some platforms:
|
|
FreeBSD 8.2, OpenBSD 4.7, MacOS X 10.5.
|
|
@item
|
|
This function fails to return a string for out-of-range integers on
|
|
some platforms:
|
|
HP-UX 11, IRIX 6.5, Solaris 8.
|
|
(Some return NULL which is a POSIX violation, others return the empty
|
|
string which is valid but not as useful); this can still cause bugs
|
|
because most programs call @code{strerror} without setting and testing
|
|
@code{errno}.)
