Function Documentation

actf_fld_loc_origin()

enum actf_fld_loc_origin actf_fld_loc_origin

(

const actf_fld_loc *

loc

)

Get the origin of the field location.

Parameters

loc	the field location

Returns

the origin

actf_fld_loc_path()

char ** actf_fld_loc_path

(

const actf_fld_loc *

loc

)

Get the path of a field location.

Each path element is either a string denoting the name of a structure field member to follow or null which means refers to the parent structure field of the current locating context.

Parameters

loc	the field location

Returns

the list of path elements, length is retrieved from actf_fld_loc_path_len().

actf_fld_loc_path_len()

size_t actf_fld_loc_path_len

(

const actf_fld_loc *

loc

)

Get the number of elements in the field location path.

Parameters

loc	the field location

Returns

the number of elements in the path
