hi everyone,

my question is somewhat conceptual, how is parent process' data shared with child process created by a "fork()" call or with a thread created by "pthread_create()"

for example, are global variables directly passed into child process and if so, does modification on that variable made by child process effect value of it in parent process?

i appreciate partial and complete answers in advance, if i'm missing any existing resource, i'm sorry, i've done some search on google but couldn't find good results

thanks again for your time and answers
