Linux supports different execution domains, or
personalities, for each process. Among other things,
execution domains tell Linux how to map signal numbers into
signal actions. The execution domain system allows Linux to
provide limited support for binaries compiled under other
UNIX-like operating systems.
This function will return the current personality() when persona equals 0xffffffff.
Otherwise, it will make the execution domain referenced by
persona the new
execution domain of the calling process.
RETURN VALUE
On success, the previous persona is returned. On error,
−1 is returned, and errno
is set appropriately.
ERRORS
EINVAL
The kernel was unable to change the personality.
CONFORMING TO
personality() is
Linux-specific and should not be used in programs intended to
be portable.
