Remarks

The following table lists the instruction's hexadecimal and Microsoft Intermediate Language (MSIL) assembly format, along with a brief reference summary:

Format	Assembly Format	Description
0F < unsigned int8 >	ldarga.s index	Fetch the address of argument indexed by index, short form.

The stack transitional behavior, in sequential order, is:

1. The address addr of the argument indexed by index is pushed onto the stack.

ldarga.s (the short form of ldarga) should be used for argument numbers 0 through 255, and is a more efficient encoding.

The ldarga.s instruction fetches the address (of type*) of the argument indexed by index, where arguments are indexed from 0 onwards. The address addr is always aligned to a natural boundary on the target machine.

For procedures that take a variable-length argument list, the ldarga.s instruction can be used only for the initial fixed arguments, not those in the variable part of the signature.

ldarga.s is used for by-ref parameter passing. For other cases, Ldarg_S and Starg_S should be used.

The following Emit method overload can use the ldarga.s opcode:
