Hey all,
I ran some simulations, of which the output is 100s of files. I've used grep to extract the vital information needed from the files. This has made my task somewhat easier. But I still need to perform some mathematical calculations (average and geometrical average) on the results of the... (9 Replies)

alloc_unr
ALLOC_UNR(9) BSD Kernel Developer's Manual ALLOC_UNR(9)NAME
new_unrhdr, delete_unrhdr, alloc_unr, free_unr -- kernel unit number allocator
SYNOPSIS
#include <sys/systm.h>
struct unrhdr *
new_unrhdr(int low, int high, struct mtx *mutex);
void
delete_unrhdr(struct unrhdr *uh);
int
alloc_unr(struct unrhdr *uh);
int
alloc_unrl(struct unrhdr *uh);
void
free_unr(struct unrhdr *uh, u_int item);
DESCRIPTION
The kernel unit number allocator is a generic facility, which allows to allocate unit numbers within a specified range.
new_unrhdr(low, high, mutex)
Initialize a new unit number allocator entity. The low and high arguments specify minimum and maximum number of unit numbers. There
is no cost associated with the range of unit numbers, so unless the resource really is finite, INT_MAX can be used. If mutex is not
NULL, it is used for locking when allocating and freeing units. Otherwise, internal mutex is used.
delete_unrhdr(uh)
Destroy specified unit number allocator entity.
alloc_unr(uh)
Return a new unit number. The lowest free number is always allocated. This function does not allocate memory and never sleeps, how-
ever it may block on a mutex. If no free unit numbers are left, -1 is returned.
alloc_unrl(uh)
Same as alloc_unr() except that mutex is assumed to be already locked and thus is not used.
free_unr(uh, item)
Free a previously allocated unit number. This function may require allocating memory, and thus it can sleep. There is no pre-locked
variant.
CODE REFERENCES
The above functions are implemented in sys/kern/subr_unit.c.
HISTORY
Kernel unit number allocator first appeared in FreeBSD 6.0.
