PERSONALITY(2) Linux Programmer's Manual PERSONALITY(2)
personality - set the process execution domain
#include <sys/personality.h>
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.
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.
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.
