This graph shows which files directly or indirectly include this file:

Macros
#define	MEM_SEEK_SET (0)
	A constant to specify that the offset is relative to the start of the stream.

#define	MEM_SEEK_CUR (1)
	A constant to specify that the offset is relative to the current position indicator.

#define	MEM_SEEK_END (2)
	A constant to specify that the offset is relative to the end of the stream.

Functions
void	mfopen_mem (MemFile mf, uint8_t p, size_t size)
	Open memory image in ROM/RAM as stream.

void	mfopen_bmem (MemFile *mf, bmemptr_t p, uint32_t size)
	Open memory image in banked memory (MegaROM) as stream.

void	mfslice (MemFile dst, const MemFile src, long size)
	Open a new stream with the specified size range from the current position.

bool	mfeof (MemFile *mf)
	Return `true` if reached to the end of stream.

uint8_t	mfread_u8 (MemFile *mf)
	Read the next byte from stream pointed by `mf`.

size_t	mfread (MemFile mf, void ptr, size_t size)
	Read some bytes from stream pointed by `mf`.

uint16_t	mfread_u16 (MemFile *mf)
	Read the next 16-bit of little-endian value from stream pointed by `mf`.

uint32_t	mfread_u32 (MemFile *mf)
	Read the next 32-bit of little-endian value from stream pointed by `mf`.

void	mfseek (MemFile *mf, long offset, int whence)
	Set the stream position indicator for the stream pointed by `mf`.

void	mfgetpos (MemFile mf, mempos_t pos)
	Get the stream position indicator of the stream pointed by `mf`.

void	mfsetpos (MemFile mf, const mempos_t pos)
	Set the stream position indicator of the stream pointed by `mf`.

void	mfsetpos2 (MemFile mf, const mempos_t base, long offset)
	Set the stream position indicator of the stream pointed by `mf`.
