... ute_name_index' é um índice dentro da Constant Pool que aponta para uma estrutura do tipo Utf8_info e que contém o nome do atributo, conforme nos #defines mostrados acima. O campo 'attribute_length' define quantos bytes a estrutura do atributo específico que vem a seguir, possui. Na sequência irei falar dos atributos que fazem parte da especificação Java 2. Os atributos 'EnclosingMethod' e 'StackMapTable', nos dias de hoje, devem ser obrigatoriamente reconhecidos e interpretados de acordo pela JVM. Os outros atributos são opcionais, devendo ser lidos porém podendo ser ignorados. 6.1. ConstantValue_attribute typedef struct ...

... en use: set_value(multi); Now, within the function we have used the values #defined by ROWS and COLS that set the limits on the for loops. But, these #defines are just constants as far as the compiler is concerned, i.e. there is nothing to connect them to the array size within the function. row and col are local variables, of course. The formal parameter definition permits the compiler to determine the characteristics associated with the pointer value that will be passed at run time. We really don’t need the first dimension and, as will be seen later, there are occasions where we would prefer not to define it within the parameter definition, out of h ...

... tory. The DataDirectory is an array of 16 structures. Each array entry has a predefined meaning for what it refers to. The IMAGE_DIRECTORY_ENTRY_ xxx #defines are array indexes into the DataDirectory (from 0 to 15). The most interesting value here (for our goals) is obviously the AddressOfEntryPoint, which we will discuss later. The ImageBase normally doesn't differ from the standard, but when it does, it's important to know when Appending to the PE file (or employing EPO techniques for that matter) The Section and File Alignments are important in the perspective that they are needed to create a proper PE image. Now, let us take a look at that intere ...

... processor. The preprocessor accepts source code as input and is responsible for removing componenets and intepreting preprocessor directives (such as #defines and macros, and anything else with # at its start for that matter). The next stage in compilation is the compiler. All this does is translate the source code sent to it from the preprocessor to assembly code. Very good. Next. The assembler comes next, it creates object code. The last step in C compilation is the linker editor, which adds libraries, and external functions to the main() function, it also resolves any external variables. After this has been done, an executable file is produced. Th ...

... variety of routines: filling, adding, subtracting, calling functions on each element, scaling by constants, etc. All are implemented as code macros (#defines), and use a uniform naming convention. The routines are very portable and have been tested with several compilers including Microsoft C v5.0, Turbo C v1.5 and Aztec v3.40b. The disk contains source code, documentation, and sample programs. For more details see the narrative description of this package in Section 2. CUG274.01-ARRAY.ART doc Article on Arrays for C. Introduction, overview, usage, and quick summary of "Arrays for C" functions. Also describes example routines and customization optio ...
