What is null?
it said in my iPhone "null would like to access Ur twitter accounts,what does that mean?
"null" means the information required to fill that blank space is also blank. The software does not know where the request is coming from. I would not recommend allowing access unless YOU specifically ran an app that would use Twitter information. If this came out of nowhere, you might have a corrupt app or something.
NULL Macro is simply what is defined as 0 in a macro provided by the library
may be an application.
"null" is "zero".
