#define, except that since it is interpreted by the compiler, it can cope with textual substitutions that are beyond the capabilities of the preprocessor. For example, typedef int (*PFI)(char *, char *); creates the type PFI, for ``pointer to function (of two char * arguments) returning...
Before issuing the VDEFINE service request (with the LIST parameter specified) the function must create two arrays to specify the formats and lengths of the variables to be defined. The first array defines, in sequence, the format (character string, fixed binary, and so forth) of each variabl...
The canvas updates to show the newly added field, located within an object that is namespaced to your unique tenant ID (shown as_tenantIdin the example below). All custom fields that are added to a schema are automatically placed within this namespace to prevent conflicts with other fields...
If omitted, perf probe automatically set the type based on debuginfo. You can specify string type only for the local variable or structure member which is an array of or a pointer to char or unsigned char type. On x86 systems %REG is always the short form of the register: for example...

An example of information that the publisher must define relates to the use ofpointersto pass data to functions. A pointer is a location in memory that indicates the start of a block of data. To pass this data to MATLAB safely, the publisher must specify the size of the data. The functi...
When you're using C++\CLI to define types, the this pointer in a reference type is of type handle. The this pointer in a value type is of type interior pointer.These different semantics of the this pointer can cause unexpected behavior when a default indexer is called. The next example ...
The following is what Lars wrote, but it also illustrates the use of pointer types as well. I did not illustrate all the advantages of using pointers, I will leave that discovery up to you. One advantage is it makes things easire if you desire to have ...
From a managed component you can call a native function with function pointer parameters where the native function then can call the member function of the managed component's delegate. This sample creates the .dll that exports the native function: ...
Currently adding to pointers doesn't work: stdin:1:37-38: ERROR: The + operator can not be used on expressions of types cast, integer BEGIN { $a = (uint16*) 123; $b = $a + 5; } In C adding to a pointer uses the pointee size to increment,...
