Gets the default file translation mode for file I/O operations.
Returns zero if successful; an error code on failure. If pmode is NULL, the invalid parameter handler is invoked as described in Parameter Validation. If execution is allowed to continue, errno is set to EINVAL and the function returns EINVAL.
The function gets the value of the _fmode global variable. This variable specifies the default file translation mode for both low-level and stream file I/O operations, such as _open, _pipe, fopen, and freopen.
