dereferencing

Additionally, local variables do not properly dereference handles when they go out of scope.

Limit pointer use to a single dereference, and do not use function pointers.

Many other operators exist to dereference pointers, and this is of significant importance especially in object-oriented languages.

A typical example of a problem detected would be a variable dereference that occurs before the variable is assigned a value.

In some languages, a pointer can reference another pointer, requiring multiple dereference operations to get to the original value.

For C and C++, bounds checking can be performed at pointer calculation time or at dereference time.

However, due to its pointer dereference syntax a dynamic array could be implemented with memory management functions, usually those from .

Pointers can of course reference other pointers, and in such cases, multiple applications of the dereference operator are needed.

That may sound obvious, but certainly isn't a given in classic Mac OS where you're always one bad pointer dereference away from a reboot.

In order to accomplish that task, the unary dereference operator, denoted by an asterisk (*), is used.

E.g. is synonymous with , meaning , which says "dereference the value stored at ", in this case .

To dereference assigned objects the array index operator, the property operator or the parameterized property of the .

STEVE: "The tenth issue is caused by an error while processing Director files during a memory dereference.

Both are illustrated in the following C snippet where minimal evaluation prevents both null pointer dereference and excess memory fetches:

In some programming languages such as the C, C++, and Go programming languages, the asterisk is used to dereference or to declare a pointer variable.

For example, in a shell script is the dereference operator applied to the variable , while in Perl is a scalar variable called .

These may include operators which reference or dereference pointer (computing)s, which access Array data type elements, or get the sizeof a data type.

Depending on the operating system, the CPU can automatically detect such an invalid access (e. g. for the null value: a null pointer dereference error).

"The future" or not, it's getting a bit silly for GUI application developers to perpetually be one bad pointer dereference away from scribbling all over their application's memory.

A null pointer dereference error in CUPS, which is the Common Unix Printing System that the Mac uses.

H (dereference) - makes the cp command follow symbolic links (symlinks) so that the destination has the target file rather than a symlink to the target.

A virtual call requires at least an extra indexed dereference, and sometimes a "fixup" addition, compared to a non-virtual call, which is simply a jump to a compiled-in pointer.

The dereference operator or indirection operator, denoted by "" (i.e. an asterisk), is a unary operator found in C-like languages that include pointer variables.

In C++, a class can overload all of the pointer operations, so an iterator can be implemented that acts more or less like a pointer, complete with dereference, increment, and decrement.

Pointers are often stored in a format similar to an integer; however, attempting to dereference or "look up" a pointer whose value was never a valid memory address would cause a program to crash.
