Bss Section In Embedded

Some c run time systems may allow part of the bss segment not to be initialized.

Bss section in embedded. In embedded software the bss segment is mapped into memory that is initialized to zero by the c run time system before main is entered. Can anyone please tell me the utility of bss section. In embedded software the bss segment is mapped into memory that is initialized to zero by the c run time system before main is entered.

Would be contained in the bss segment. What it actually stands for block started by symbol. In the above code un initialized after initializing it to zero and another initialized are stored in bss section.

Stores uninitialised data but why can t it be stored in data segment together with other initialised data. Uninitialized data segment bss this segment stores all global and local variables that are initialized to zero or do not have explicit initialization in the source code. The bss segment contains all global variables and static variables that are initialized to zero or do not have explicit initialization in source code.

Reply start a new thread. Hello guys i am new to this group and embedded domain. C variables must explicitly be placed into that portion of the bss segment.

The memory locations of variables stored in this segment are initialized to zero before the execution of the program starts. What is the advantage need of bss segment. For instance a variable defined as static int i.

The bss segment also known as uninitialized data is usually adjacent to the data segment.
