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.
personality
() is
Linux-specific and should not be used in programs intended to
be portable.
