Description
The behavior of this function is undefined unless its control parameter is set to a specific value.
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.
It is unusual for this function to be called directly. It is almost always invoked through a macro defined in a system header file, and the macro ensures that the following constraints are met:
The value 1 must be passed to the third 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
