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

Syntax

 #include <as400_protos.h>

 size_t size_ILEarglist(const arg_type_t  *signature);

  Default Public Authority: *USE

  Library: Standard C Library (libc.a)

  Threadsafe: Yes

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)
