Function Documentation

build_resource_fork()

static void build_resource_fork ( struct vol *  vol, const unsigned char *  icn_hash, const unsigned char *  icl4, const unsigned char *  icl8  )

static

Build the Macintosh resource fork binary data containing ICN#, icl4, and icl8.

icn_hash: 256-byte ICN# resource (icon bitmap + mask) icl4: 512-byte icl4 resource (32x32 4-bit color icon) icl8: 1024-byte icl8 resource (32x32 8-bit color icon)

is_virtual_icon_name()

int is_virtual_icon_name

const char *

name

put_u16()

static void put_u16 ( unsigned char *  buf, uint16_t  val  )

static

Write a big-endian uint16_t to buf

put_u32()

static void put_u32 ( unsigned char *  buf, uint32_t  val  )

static

Write a big-endian uint32_t to buf

real_icon_exists()

virtual_icon_enabled()

virtual_icon_get_rfork()

const unsigned char * virtual_icon_get_rfork	(	const struct vol *	vol,
		size_t *	outlen
	)

virtual_icon_getfilparams()

int virtual_icon_getfilparams	(	const AFPObj *	obj,
		struct vol *	vol,
		uint16_t	bitmap,
		char *	buf,
		size_t *	buflen
	)

Synthesize AFP file parameters for the virtual Icon\r file.

This fills the reply buffer with parameters matching the requested bitmap, just as getmetadata/getfilparams would for a real file.
