unsigned int KISS();
unsigned int devrand();
int main( int argc, char** argv )
{
int i, j = 1;

I have an 10 element array containing numbers, I want the start and end index in the array for which the values lie between DIST1 and DIST2. It is not working quite right. I also might want a value of 0 if I cannot find an index.
V=(/10.0,20.0,30.0,40.0,50.0,60.0,70.0,80.0,90.0,100.0/)

I'm doing a little work on assessing and improving server stability. As part of that, we're reviewing the contents of /proc/slabinfo. We see that sometimes a certain metric-- say, buffer_head-- spike prior to server instability. We're interested in learning what contributes to that as we trace... (0 Replies)
i would like to search for a letter in a string and get its index position.
example:
name='john'
pos=$(expr index $name o)
the result will be equal to 2 (2nd position)
how do you make this thing not case sensitive?
example:
name='john'
pos=$(expr index $name O)

ARRAYS
XPC arrays are collections of XPC objects ordered by index. The index is zero-based. XPC arrays are contiguous, and values must exist at all
indexes between zero and the greatest index of the array. A hole in the array can be simulated by using a null object as returned by
xpc_null_create(3).
CREATION
The xpc_array_create() function returns a newly created array. The caller may optionally provide objects, a C array of XPC object references,
to initialize the array. The count is used to specify the size of the C array. If objects is NULL, then count must be zero. If count speci-
fies more elements than are actually present in values or if values is NULL and count is non-zero, the behavior is undefined.
GETTING AND SETTING VALUES
The xpc_array_append_value() function may be used to append a value to the end of an array. This operation increases the count of the values
in the array by one.
The value of a specific index in the array may be set using the xpc_array_set_value() function. The value must be non-NULL, and the index
must already exist (i.e. less than the count provided at creation or extended through previous append operations).
The value at a specific index of an array may be retrieved using the xpc_array_get_value() function. The result of getting a non-existing
index (i.e. one that was not specified at creation or through a previous append operation) in undefined.
PRIMITIVE GET AND SET FUNCTIONS
Various functions exist for retrieving primitive C and operating system types directly from an array without the need for an intermediate
boxed object. See xpc_object(3) for more information.
The special XPC_ARRAY_APPEND constant may be used to append a value to the end of the array instead of operating on a specific index.
