c++ - the variable with the same name in multi threads environment -


i have class file. created 2 threads , b. in , b, each thread, create auto varible file myfile. , , b operate it. secure? lead inconsistent of data?

  • if static, referring same global address.

from file access perspective, depends if same file, , if writing or not.
