Note: #pragma is compiler specific, so syntax may vary for your compiler.

The DATA_SECTION pragma allocates space for the symbol in a section called section name. The syntax for the pragma in C could be:

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

The syntax for the pragma in C++ could be:

#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.

The CODE_SECTION pragma allocates space for the func in a section named section name. The CODE_SECTION pragma is useful if you have code objects that you want to link into an area separate from the .text section. The syntax of the pragma in C could be:

#pragma CODE_SECTION (func, "section name")

The syntax of the pragma in C++ could be:

#pragma CODE_SECTION ("section name")
