size_ILEarglist()--Compute ILE Argument List Size for IBM PASE for i

 #include <as400_protos.h>

 size_t size_ILEarglist(const arg_type_t  *signature);  

Note: This function can only be used in an IBM^® i PASE program. See the IBM PASE for i topic collection for more information about creating IBM PASE for i programs.

The size_ILEarglist() function computes the number of bytes of memory required to build an ILE argument list for a specific function signature.

Parameters

signature

(Input) Pointer to a list of arg_type_t values that specify the sequence and type of arguments passed to the ILE procedure. ILE procedures can accept a maximum of 400 arguments. The actual number of arguments processed by the size_ILEarglist function is determined by the number of entries in the signature list, which is determined by the location of the first ARG_END value in the list. The following values are supported in the signature list:

ARG_END (0)	Specifies the end of the signature list.
ARG_INT8 (-1)	Signed 1-byte integer argument.
ARG_UINT8 (-2)	Unsigned 1-byte integer argument.
ARG_INT16 (-3)	Signed 2-byte integer argument.
ARG_UINT16 (-4)	Unsigned 2-byte integer argument.
ARG_INT32 (-5)	Signed 4-byte integer argument.
ARG_UINT32 (-6)	Unsigned 4-byte integer argument.
ARG_INT64 (-7)	Signed 8-byte integer argument.
ARG_UINT64 (-8)	Unsigned 8-byte integer argument.
ARG_FLOAT32 (-9)	4-byte floating-point argument.
ARG_FLOAT64 (-10)	8-byte floating-point argument.
ARG_FLOAT128 (-18)	16-byte floating-point argument.
ARG_MEMPTR (-11)	The argument is a field of type ILEpointer.
ARG_SPCPTR (-12)	The argument is a field of type ILEpointer.
ARG_SPCPTRI (-16)	The argument is a field of type ILEpointer.
ARG_OPENPTR (-13)	The argument is a field of type ILEpointer.
ARG_OPENPTRI (-17)	The argument is a field of type ILEpointer.
ARG_MEMTS64 (-14)	The argument is a field of type ts64_t.
ARG_TS64PTR (-15)	The argument is a field of type ts64_t.
Any positive number (1-32767)	The argument is an aggregate (structure or union). The value in the signature list is the length, in bytes, of the aggregate.

Authorities

size_ILEarglist requires no authority.

Return Value

size_ILEarglist returns the number of bytes required to build the ILE argument list (including storage for the ILEarglist_base type and any necessary bytes skipped for alignment between arguments), or zero if an error was detected in the signature list.
