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