Detailed Description

Function Documentation

cbmimage_i_d1m_d2m_d4m_chdir()

static int cbmimage_i_d1m_d2m_d4m_chdir ( cbmimage_image_settings * settings, cbmimage_dir_entry * dir_entry )

static

function for chdir'ing in a D1M, D2M or D4M image

Parameters

[in]	settings	pointer to the image data internal settings
[in]	dir_entry	pointer to the dir_entry to which to chdir.

Returns

• 0 if no error occurred
• != 0 if an error occurred

Remarks

• This function tests if the directory entry is actually a directory to which it can change. If it is not valid, it should return with an error value != 0. In this case, the chdir is aborted and returns with an error, too.

cbmimage_i_d1m_d2m_d4m_get_geos_infoblock()

static int cbmimage_i_d1m_d2m_d4m_get_geos_infoblock ( cbmimage_image_settings * settings )

static

get the GEOS info block of this image has one

Parameters

[in]

settings

pointer to the image data internal settings

Returns

• 0 if this is a non-GEOS image
• != 0 if this is a GEOS image

cbmimage_i_d1m_d2m_d4m_image_create()

void cbmimage_i_d1m_d2m_d4m_image_create	(	cbmimage_fileimage *	image,
		cbmimage_imagetype	imagetype,
		unsigned char *	imagetype_name,
		uint8_t	maxsectors )

create structures for a D1M, D2M and D4M image

Parameters

[in]	image	pointer to the image data
[in]	imagetype	The type of image that should be created
[in]	imagetype_name	The name of the image type that should be stored in the images. This value is only informational and can be asked for by the user; it is not used internally.
[in]	maxsectors	The number of sectors of this image
