Detailed Description

Function Documentation

cbmimage_i_d81_chdir()

static int cbmimage_i_d81_chdir ( cbmimage_image_settings * settings, cbmimage_dir_entry * dir_entry )

static

function for chdir'ing in a 1581 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.
