The x1f4_lxpoll_type record lists the application concerns related to the control library objects generation.

The fields that are always interpreted by the control library constructor function are:

polltype_set

specifies the type id to use for the introduced ‘dispatch’ type (some number conveniencing the application, greater than X1f4_E4_LAST) as:

See Symbolic Types.

type

the id

sidelink_set

specifies the type ids to assume for the referred ‘date’ and ‘file’ as:

See Symbolic Types.

date

the ‘date’ id

See Date And Time Library.

file

the ‘file’ id

See File Library.

autolink_set

specifies the temporaries allocator.

See struct x1f4_frame_type.

See Temporaries.

See Temporaries Allocator Construct.

datatype_set

specifies the data types that are to receive special consideration for operations such as setting reference function parameters as:

miss

the data types count

nodetype_data

the array of struct x1f4_nodetype_type record data type descriptions, miss long. The data type descriptions detail such data operations as copying and freeing along data type identification (data type name and data type id).

See struct x1f4_nodetype_type.

The array is not used outside the trap library object construction, no references inside it are recorded, it may come out of existence once the library object construction completed.

The fields that are interpreted only if so requested are:

See Control Library Generation Flags.

codelink_set

specifies the library data memory allocator (allocates memory for the library object construction purposes only).

See struct x1f4_trans_type.

See Memory Allocator Construct.

resource_set

specifies the data memory allocator (allocates memory for the data created while executing programs).

See struct x1f4_trans_type.

See Memory Allocator Construct.

textflat_set

specifies the error reporter.

See struct x1f4_track_type.

See Error Reporter Construct.

missbail_set

specifies the consolidated disposal manager as:

miss

the object registration method

fine

the non recursive object registration method

call

the object deregistration method

text

the consolidated disposal context

See Consolidated Disposal.

See Consolidated Disposal Manager Construct.

eelookup_set

specifies a name lookup context as:

eelookup_data

the data type name lookup context, used for both error reporting and data type name retrieval

See struct x1f4_eelookup_type.

position_set

specifies the polling interruption cure as:

call

the method to call (NULL for no method). It is assumed to return zero for success, not zero otherwise. Failures are treated as any execution failure, error class indications are observed.

See Error Classes.

text

the only parameter of the called method

class

the address of the flag to test on whether calling the method is in order (with non zero values requesting a call).

See Signal Reception.
