Function Documentation

bfx_build_loops()

BFX_Error bfx_build_loops

(

BFX *

bfx

)

Builds the loop structure for the BFX instance.

This function scans the BFX program and constructs the necessary data structures to efficiently handle loop constructs ('[' and ']'). It ensures that matching brackets are correctly paired, allowing for proper execution flow during interpretation.

Parameters

bfx	The BFX instance to build loops for.

Note

This function does not return a value. If an error occurs (such as exceeding MAX_LOOPS), it prints an error message and terminates the program using exit(EXIT_FAILURE).

bfx_parse_ops()

BFX_Error bfx_parse_ops	(	BFX *	bfx,
		BFX_Error(*[128])(BFX *, BFX_FileIndex *)	ops
	)

Executes operations on the BFX instance.

Parameters

bfx	The BFX instance to run
ops	Operation map

Returns

Error code
