Public Shared ReadOnly Ldarga_S As OpCode
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:
- The address
addr
of the argument indexed byindex
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:
