L_BOOL LVectorFile::IsValid(L_VOID)
Determines whether the LVectorFile object is ready to be used.
Returns
|
TRUE |
The LVectorFile object is ready to be used. |
|
FALSE |
The LVectorFile object is not ready to be used. |
Comments
Before you can use some of the file functions, a vector and a filename must be associated with the class object. Until you have associated a vector and a filename with the LVectorFile object, the object is considered invalid.
The function will return TRUE only if both the filename and the vector have been set and are valid.
