Function Documentation

dpkg_fsys_get_dir()

const char * dpkg_fsys_get_dir

(

void

)

Get current on-disk filesystem root directory.

This function will take care of initializing the directory if it has not been initialized before.

Returns

The current filesystem root directory.

Referenced by conffderef(), and dpkg_fsys_get_path().

Here is the caller graph for this function:

dpkg_fsys_get_path()

char * dpkg_fsys_get_path

(

const char *

pathpart

)

Get a pathname to the current on-disk filesystem root directory.

This function returns an allocated string, which should be freed with free(2).

Parameters

pathpart

The pathpart to append to the new pathname.

Returns

The newly allocated pathname.

dpkg_fsys_set_dir()

const char * dpkg_fsys_set_dir

(

const char *

dir

)

Set current on-disk filesystem root directory.

This function can be used to set the directory to a new value, or to reset it to a default value if dir is NULL.

Parameters

dir	The new filesystem root directory, or NULL to set to default.

Returns

The new filesystem root directory.
