io_uring_r...personality(3) liburing Manual io_uring_r...personality(3)
io_uring_register_personality - register credentials with io_uring
#include <liburing.h>
int io_uring_register_personality(struct io_uring *ring);
The io_uring_register_personality(3) function registers the
credentials of the calling application with the io_uring instance
specified by ring. This allows a ring to be shared between
separate users or processes while maintaining credential
separation.
The returned personality ID can be used in the personality field
of a submission queue entry to execute that request with the
registered credentials.
Returns a positive personality ID on success that can be used in
future operations. On error, a negative errno value is returned.
