int personality(unsigned long
persona);
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.
If persona is not 0xffffffff, then personality() sets
the caller’s execution domain to the value specified by persona. Specifying
persona as 0xffffffff provides a way of retrieving the current persona
without changing it.
A list of the available execution domains can be found
in <sys/personality.h>.
On success, the previous persona is returned.
On error, -1 is returned, and errno is set appropriately.
- EINVAL
- The
kernel was unable to change the personality.
personality()
is Linux-specific and should not be used in programs intended to be portable.
