procedure: (rlimit RESOURCE [HARD?])

Returns the current limit for the resource RESOURCE, which should be one of the resource-identifiers listed below. By default the soft limit is returned, but if HARD? is given and true, the current hard limit is returned. See the getrlimit(2) man page for more information.

Note that if no limit is set, +inf. (inifinity) will be returned.

Here is a list of available resources. Some resource types mot be available on every platform.

rlimit/core	core file size
rlimit/cpu	CPU time limit in seconds
rlimit/data	maximum size of data segment
rlimit/fsize	maximum size of created files
rlimit/locks	maximum number of file locks and fcntl leases
rlimit/memlock	maximum size of locked vm memory
rlimit/nofile	maximum file-descriptor
rlimit/ofile	equivalent to rlimit/nofile
rlimit/nproc	maximum number of created processes
rlimit/rss	limit in pages for resident set size
rlimit/stack	maximum stack size
rlimit/vmem	maximum virtual memory size

setter: (set! (rlimit RESOURCE [HARD?]) VALUE)

Sets the soft or hard resource limit. A value if +inf. disables the limit completely. A value of false is equivalent to zero.
