Before our startup file clears BSS and copies are implemented by the way of assembly, however, we are able to use the C language without using the assembler:First look at the connection script: sections{. = 0x30000000 ; __code_start =.; . = ALIGN (4 * (. Text)}. = ALIGN (4 * (. Rodata)}. = ALIGN (4 * = ALIGN (4 =.; . BSS: { * (. BSS)
1. Uninitialized global variable (. BSS segment)The BSS segment is used to store global variables that have not been initialized and have been initialized to 0 . The following example code:#include Compile and view:$ gcc-g mainbss.c-o mainbss$ ls-l mainbss-rwxrwxr-x. 1 hy hy 8330 Apr 19:33 mainbss$ objdump-h mainbss |grep BSSMAINBSS: file format elf32-i386.

Linux the segment management,BSS A segment (BSS segment) usually refers to an area of memory that is used to hold uninitialized global variables in the program. BSS is the abbreviation for English block Started by symbol. BSS segments belong to static memory allocations.This segment is used to store uninitialized globa

Different compiler may have slightly different allocations for storage during compilation, but the basic structure is roughly the same.Broadly, it can be divided into three segments: text, data, and BSS.The text section is used for storing code, which is typically mapped as read-only in memory, but data and BSS are writable.Data storage is usually divided into the following sections:1, stack: Automatically allocated by the compiler, save the function
BSS segment in program, data segment, code snippet (. Text), heap (heap), stack (stack). BSS segment: Uninitialized and initialized to 0 global variables and static local variables (static) initialized to 0 in the program. Data segment: Non-zero initialized global variables and non-zero initialized static local variables (static) in the programCode Snippet: the place (. Text field) where the code is stored,
In memory management, memory is divided into: System reserve, code area, global variable area, heap, and stack.The global variable area can also be divided into: Data segment and BSS segment.The data segment is used to store initialized global variables, static variables, and literal constants.The BSS segment is used to store uninitialized global variables, static variables."Program Instance 1"#include usin
BSS segments: In a segmented memory management architecture, BSS segments (BSS segments) are generally a memory area used to store uninitialized global variables in the program. BSS is short for block started by symbol. BSS segments belong to static memory allocation.

Executable programs include BSS segments, data segments, and code segments (also called text segments ). 1. bssbss (block started by symbol) is usually a memory area used to store uninitialized global variables and static variables in the program. Features: read/write, BSS segments are automatically cleared before the program is executed. Therefore, the uninitialized global variables are 0 before the progra
A program is generally divided into three sections: Text, data, and BSS. Text: it refers to the code of the program. It is determined during compilation, read-only, and data segment: data that can be determined at the compilation stage (rather than the runtime). readable and writable data is usually referred to as the static storage area. The global and static variables with initial values are stored in this area, constants are also stored in the
ProgramThe compiled target file contains at least three segments:. Text,. Data, And. BSS. The structure of the three segments is as follows:
Where. Text isCodeSegment, which is read-only .. The BSS segment contains uninitialized global and static variables in the program.
The data segment consists of three parts: heap, stack, and static data zone.

Objective:Whether it is the pursuit of retro analog tones or high-precision transparent sound quality, modern computer music production of the middle of the new EQ plug-in with its super-frequency shaping and personalized features for the tone of the touch-up and remodeling provides unlimited possibilities.Although EQ is not the most complex of audio engineering tools, the use of errors does have a big impa
In Word2003, a single melody or multipart music notation can be made by editing the EQ field code. "EQ Domain" is a mathematical formula editing function in Word2003, and many complex mathematical formulae can be produced by using EQ field. Making music using EQ domain notation mainly uses two kinds of switches in
The first 3 methods of these 4 methods are commonly seen, but the slice method may be thought of as an array method, in fact, Slice is also a prototype of jquery, but the underlying approach is to serve other methods (more specifically, the EQ Method of service), First of all, look at these methods of how the foreground is used;EQ Overviewgets the nth elementParametersAn integer that indicates the position
I believe most people will make mistakes in these two methods. You can view the API documentation carefully. Eq returns a jquery object, and get returns an array of html objects. For example:
YuUse eq to obtain the color value of the first p Tag:
$ ("P" ).eq(0).css ("color") // because eq (num) returns a jq object, th
: the EQ () selector selects the element with the specified index value.The index value starts at 0, and the index value of all first elements is 0 (not 1).Get (Index) gets one of the matching elements. The index represents the element that gets the first few matches.This allows you to select an actual DOM element and manipulate it directly, rather than through the JQuery function. $ (this). Get (0) is equivalent to $ (this) [0].Here's a simple code t
I have never understood eq in jquery, but I found that eq is used in many places. I will share with you several examples below.
Definition and usage

The index value starts from 0, and the index value of all the first element is 0 (not 1 ).
