General C-Compiled execution statements are compiled into their code, saved in the. Text field, both the initialized global variable and the local static variable are saved in the. Data segment, and the uninitialized global and local static variables are generally placed in the. BSS section. We know that uninitialized global variables and local static variables default to 0, they can be stored in the. Data segment, but their values are 0, which is not

A program is essentially composed of BSS, data, and text segments three. This concept is very important in the current computer programming, and it is very important in the design of the embedded system, which involves the memory size allocation when the embedded system executes, the storage unit occupies the space size problem. BSS segment: In the architecture that uses the segment-memory manageme

A program is essentially composed of BSS, data, and text segments three. You can see that an executable program is divided into sections of code, data areas, and uninitialized data areas when it is stored (not being transferred into memory). BSS segment (uninitialized data area): In a schema with segment memory management, BSS (

execute, because the bottom is all 0, and finally jump to the function of the main place to continue execution.4.2.4 reads the system () address and the string "/bin/sh" using Read (). In BSS segmentSince the parameters of the 64-bit system are not stored on the stack, but are passed through the register, plus the ASLR is turned on, you need to find a fixed location to save the parameters. The BSS section

SAA-SQL access advisor (oracle 11.2 and later), saa-sqladvisor I recently used SAA and found that many blogs on the Internet actually have problems using it in subsequent versions after oracle 11.2, Either the version change syntax is changed or incomplete.

superior to that of the single-channel, but the storage space occupied after digitalization is twice the size of the single-channel. Ii. Sound Card drive For security considerations, Linux applications cannot directly operate hardware devices such as sound cards, but must use the driver provided by the kernel. The essence of audio programming in Linux is to use the driver to complete various operations on the sound card. Hardware control involves the operation of each bit in the register. Gener
