What is the relationship with the shell stack limit (ulimit -s ) and the stack size for threads chosen by the user with pthread_attr_setstacksize? Can the stack size for a created thread be made larger than the stack size for the parent thread? Are there any limits or defaults that users should be aware of?
I've been told that the ulimit needs to be a numerical value to be able to set a created thread's stack size to some larger number. If the ulimit is set to 'unlimited', then there is a default limit (16 MB?) on a thread's stacksize. And all of this only applies to RedHat 7.2 and beyond.
Can anyone confirm or correct this information? If I'm not running RedHat Linux, is there a particular kernel version that has support for thread stacks being different sizes (bigger) that parent stacks?
Thanks.
