Public Shared ReadOnly Ldarga 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 |
---|---|---|
FE 0A < unsigned int16 > |
ldarga index |
Fetch the address of argument indexed by index . |
The stack transitional behavior, in sequential order, is:
- The address
addr
of the argument indexed byindex
is pushed onto the stack.
The ldarga
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. The argument is stored in unmanaged memory, so the return value can be converted to an unmanaged pointer without pinning.
For procedures that take a variable-length argument list, the ldarga
instruction can be used only for the initial fixed arguments, not those in the variable part of the signature.
ldarga
is used for by-ref parameter passing. For other cases, Ldarg and Starg should be used.
The following Emit method overload can use the ldarga
opcode:
