PERSONALITY(2) Linux Programmer's Manual PERSONALITY(2)
personality - set the process execution domain
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.
personality will make the execution domain referenced by persona the new execution domain
of the current process.
On success, persona is made the new execution domain and the previous persona is returned.
On error, -1 is returned, and errno is set appropriately.
EINVAL persona does not refer to a valid execution domain.
personality is Linux-specific and should not be used in programs intended to be portable.
