Name
personality — set the process execution domain
Synopsis
#include <sys/personality.h>
int
personality( |
unsigned long |
persona) ; |
DESCRIPTION
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 current 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.
