ABSTRACT

The behavior of this function is undefined unless its control parameter is set to a specific value.

EXPLANATION

The Linux Standard Base Specification 2.0.1 for libc places constraints on the arguments to some internal functions [1]. If the constraints are not met, the behavior of the functions is not defined.


The value 1 must be passed to the first parameter (the version number) of the following file system function:


__xmknod


The value 2 must be passed to the third parameter (the group argument) of the following wide character string functions:


__wcstod_internal
__wcstof_internal
_wcstol_internal
__wcstold_internal
__wcstoul_internal


The value 3 must be passed as the first parameter (the version number) of the following file system functions:


__xstat
__lxstat
__fxstat
__xstat64
__lxstat64
__fxstat64
