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 +.B personality +when +.I persona +equals 0xffffffff. Otherwise, it will make the execution domain +referenced by +.I persona +the new execution domain of the current process. +.SH "RETURN VALUE" +On success, the previous +.I persona +is returned. On error, \-1 is returned, and +.I errno +is set appropriately. +.SH ERRORS +.TP +.B EINVAL +The kernel was unable to change the personality. +.PP +.SH FILES +.I /usr/include/linux/personality.h +.SH "CONFORMING TO" +.B personality +is Linux-specific and should not be used in programs intended to be portable. |
