_doserrno is deprecated. Use _get_errno instead.

errno_t _get_doserrno( 
   int * pValue 

[out] pValue

A pointer to an integer to be filled with the current value of the _doserrno variable.

Returns zero if successful; an error code on failure. If pValue is NULL, the invalid parameter handler is invoked as described in Parameter Validation. If execution is allowed to continue, this function sets errno to EINVAL and returns EINVAL.

Possible values of _doserrno are defined in Errno.h.
