I'm writing a program and I have the following problem:

char *tmp;
sprintf (tmp,"%ld",(long)time_stamp_for_file_name);

Could someone explain how much memory allocate for the string tmp.

How many chars are a long variable?

Thank you,

I would appreciate also a link to an exahustive resource on this kind of information.

Thank you
