Function Documentation

bitmap_clear()

void bitmap_clear

(

Environment *

_environment

)

Emit ASM implementation for BITMAP CLEAR instruction.

This instruction allows you to fill the bitmap with an empty pattern (usually zero). The filled part is exclusively that linked to the bitmap, so the color information is kept unchanged. This is the version that is recalled where the source presents the instruction with reference to a computer expression.

Precondition

Bitmap must be enabled at least once with instruction BITMAP ENABLE.

Parameters

_environment

Current calling environment

Exceptions

EXIT_FAILURE

CRITICAL: BITMAP CLEAR WITH xxx needs BITMAP ENABLED

Definition at line 122 of file bitmap_clear.c.

bitmap_clear_with()

void bitmap_clear_with	(	Environment *	_environment,
		int	_pattern )

Emit ASM implementation for BITMAP CLEAR WITH [int] instruction.

This instruction allows you to fill the bitmap with a certain pattern (usually zero is used to indicate the blank screen). The filled part is exclusively that linked to the bitmap, so the color information is kept unchanged. This is the version that is recalled where the source presents the instruction with reference to a direct pattern (e.g. 42).

Precondition

Bitmap must be enabled at least once with instruction BITMAP ENABLE.

Parameters

_environment	Current calling environment
_pattern	Pattern to use

Exceptions

EXIT_FAILURE

"BITMAP CLEAR WITH xxx needs BITMAP ENABLED"

Definition at line 60 of file bitmap_clear.c.

bitmap_clear_with_vars()

void bitmap_clear_with_vars	(	Environment *	_environment,
		char *	_pattern )

Emit ASM implementation for BITMAP CLEAR WITH [expression] instruction.

This instruction allows you to fill the bitmap with a certain pattern (usually zero is used to indicate the blank screen). The filled part is exclusively that linked to the bitmap, so the color information is kept unchanged. This is the version that is recalled where the source presents the instruction with reference to a computer expression.

Precondition

Bitmap must be enabled at least once with instruction BITMAP ENABLE.

Parameters

_environment	Current calling environment
_pattern	Pattern to use

Exceptions

EXIT_FAILURE
