Execution of the program presented in the listing above will result in output:

S=1, m=0, e=128

S=1, m=0, e=127

S=0, m=0, e=126

S=0, m=0, e=127

Processes in POSIX- compliant operating system have the property:

Communication between processes using shared memory requiers the kernel to particpate in the data writing and reading phase

The process is created when the program is loaded into memory and consists of sections of code, data, stack and optionally heap

Filature of the parent process causes the child process to terminate immediately

The child process is always a copy of the parent (its code and data cannot be changed)

C functions have the property

Arguments passed to the function can be modified while its code is being executed and are returned to the place where it is called upon completion.

Variables declared inside a function block can exist before and after the execution of the function

A function can only provide result values by returning them with a return statement

Function cannot access external variables in order to read or modify ther values

The bash shell has the following features.

It allows to define environment variables of structured types

It allows to execute sequences of user commands

It can only execute single user commands

It allows to define scalar and array type environment variables

C language data pointers have the property.

The only way to initialize pointers variables is to use one of the dynamic memory allocation functions.

When declaring a pointer variable the type of the pointer data is given, the & character and the name’

Pointer variables only store the starting address of the variable or memory area

Pointers cannot be passed to functions as arguments or returned as results

The command given below. Lm@arch:~% ls/usr/nin/|grep ‘[^e-g]grep$’

Will search the /usr/bin/directory for files with names containing “[^e-g]grep$”

Will search the /usr/bin/directory for files with names ending with phrase grep, which is not preceded by any of the characters ‘e’, ‘f’, ‘g’

Will search the /usr/bin/directory for files with names ending with grep, followed by one of the characters ‘^’ , ‘e’ , ‘f’ , ‘g’

Will search the /usr/bin/directory for files with names ending in grep, preceded by one of the characters ‘^’, ‘e’, ‘-’, ‘g’

Singely-lined list in C:

Is an unordered collection of elements of any type

Is defined in the standard library as type GSList

Performs appending an element to the end of the list as an operation with complexity O(n)

Can be defined using a structure composed of two fileds (pointer to data and to the successor), possibly supplemented with functions implementing the required operations
