personality() - Unix, Linux System Call
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.
This function will return the current
persona equals 0xffffffff. Otherwise, it will make the execution domain
persona the new execution domain of the current process.
On success, the previous
persona is returned. On error, -1 is returned, and
errno is set appropriately.
The kernel was unable to change the personality.
personality() is Linux-specific and should not be used in programs intended to be portable.
