c语言 pragma code,#pragma DATA_SECTION 和 #pragma CODE_SECTION的使用

The DATA_SECTION pragma

allocates space for the symbol in a section called section

name. The syntax for the pragma in C is:

#pragma DATA_SECTION (symbol, "section name");

The syntax for the pragma in C++ is:

#pragma DATA_SECTION ( "section name");

The DATA_SECTION pragma is useful if you have data objects that you

want to link into an area separate from the .bss section.

This directive is illustrated in the following example.

Using the DATA_SECTION Pragma

a) C source file

#pragma DATA_SECTION(bufferB, "my_sect")

char bufferA[512];

char bufferB[512]:

//

执行完此三条语句之后，数组bufferB被分配到段名为

"my_sect"的自定义段中

b) C++ source file

char bufferA[512];

#pragma DATA_SECTION("my_sect")

char bufferB[512];

c) Assembly source
