The struct x1f4_attributes_type record describes the expression interpretation context.

The fields that are always interpreted by the expression parsing functions are:

function_set

specifies the functions set as:

fix

the function specific execution context retriever method

See Per Function Execution Contexts.

get

the function look up method

context

the function look up context

See Functions.

variable_set

specifies the variables set as:

get

the variable look up method

context

the variable look up context

See Variables.

operator1s

specifies the prefix unary operators set

See Prefix Unary Operators.

operator2s

specifies the infix binary operators set

See Infix Binary Operators.

The fields that are interpreted by default or if so requested are:

terminator

indicates the character whose first occurence marks the textual expression completion

See Completions.

See Syntax.

The fields that are interpreted only if so requested are:

completion

specifies textual expression completion syntax

See Completions.

See Syntax.

bcollect_set

specifies some parsing error collector as:

eerecord_data

the very error collector

See struct x1f4_eerecord_type.

See Error Reporting.

resource_set

specifies an alternate memory manager as:

free

a memory deallocater method

link

a memory allocator method

mode

a memory reallocator method

context

the memory management context

See Memory Allocator Construct.

See Replacing Default Memory Manager.

internal_set

specifies the maximum already recorded stack sizes that needs to be updated if exceeded as:

s1st

the first stack size maximum size record address

s2nd

the second stack size maximum size record address

See Managing Stacks.

datalink_set

specifies the addresses of the stack to be used as:

v1st

the first stack address

v2nd

the second stack address

See Managing Stacks.
