The asm definition is implementation-defined. Typically, the string-literal contains assembler instructions. Some compilers extend the asm syntax to make it easier to write larger blocks of assembler code.

Example

asm("mov 4, %eax"); // GNU on Intel IA32

asm("mov eax, 4");  // Borland on Intel IA32
