On each call to GetNextVariableName() the previous -results are passed into the interface, and on output the interface returns the next variable name data. -When the entire variable list has been returned, the error EFI_NOT_FOUND is returned. - -Note that if EFI_BUFFER_TOO_SMALL is returned, the VariableName buffer was too small for the next -variable. When such an error occurs, the VariableNameSize is updated to reflect the size of buffer -needed. In all cases when calling GetNextVariableName() the VariableNameSize must not exceed the -actual buffer size that was allocated for VariableName. The VariableNameSize must not be smaller the size -of the variable name string passed to GetNextVariableName() on input in the VariableName buffer. - -To start the search, a Null-terminated string is passed in VariableName; that is, VariableName is a pointer -to a Null character.
