If memory is tight, the system will prefer to take memory -from processes which are exceeding their declared -.Dv LIM_MAXRSS. -.El -.Pp -Because this information is stored in the per-process information -this system call must be executed directly by the shell if it -is to affect all future processes created by the shell; -.Xr limit -is thus a built-in command to -.Xr csh 1 . -.Pp -The system refuses to extend the data or stack space when the limits -would be exceeded in the normal way; a -.Xr brk 2 -call fails if the data space limit is reached, or the process is -killed when the stack limit is reached (since the stack cannot be -extended, there is no way to send a signal!). -.Pp -A file -.Tn I/O -operation which would create a file which is too large -will cause a signal -.Dv SIGXFSZ -to be generated, this normally terminates -the process, but may be caught. -When the cpu time limit is exceeded, a signal -.Dv SIGXCPU -is sent to the -offending process; to allow it time to process the signal it is -given 5 seconds grace by raising the -.Tn CPU -time limit. -.Sh SEE ALSO -.Xr csh 1 -.Sh HISTORY -The -.Fn vlimit -function appeared in -.Bx 4.2 . -.Sh BUGS -.Dv LIM_NORAISE -no longer exists. - -This function has not yet been reimplemented. |
