DWARF_DIENAME(3)					   BSD Library Functions Manual 					  DWARF_DIENAME(3)

NAME

     dwarf_diename -- retrieve the name associated with a debugging information entry

LIBRARY

     DWARF Access Library (libdwarf, -ldwarf)

SYNOPSIS

     #include <libdwarf.h>

     int
     dwarf_diename(Dwarf_Die die, char **ret_name, Dwarf_Error *err);

DESCRIPTION

     Function dwarf_diename() retrieves a pointer to the NUL-terminated string associated with the DW_AT_name attribute of the debugging informa-
     tion entry descriptor referenced by argument die.	If the pointer was successfully retrieved, it is stored in the location pointed to by
     argument ret_name.

RETURN VALUES

     Function dwarf_diename() returns DW_DLV_OK on success.

     If the debugging information entry descriptor denoted by argument die does not contain a DW_AT_name attribute, the function returns
     DW_DLV_NO_ENTRY and sets argument err.  For other errors, it returns DW_DLV_ERROR and sets argument err.

ERRORS

     Function dwarf_diename() can fail with the following errors:

     [DW_DLE_ARGUMENT]	Either of arguments die or ret_name was NULL.

     [DW_DLE_NO_ENTRY]	Argument die had no DW_AT_name attribute.

DWARF_ATTR(3)						   BSD Library Functions Manual 					     DWARF_ATTR(3)

NAME

     dwarf_attr -- retrieve an attribute descriptor associated with a DWARF debugging information entry

LIBRARY

     DWARF Access Library (libdwarf, -ldwarf)

SYNOPSIS

     #include <libdwarf.h>

     int
     dwarf_attr(Dwarf_Die die, Dwarf_Half attr, Dwarf_Attribute *atp, Dwarf_Error *err);

DESCRIPTION

     Function dwarf_attr() retrieves the attribute descriptor for an attribute associated with the DWARF debugging information entry descriptor in
     argument die.

     DWARF attribute descriptors are represented by value of the opaque type Dwarf_Attribute, see dwarf(3).

     Argument attr names the desired DWARF attribute.  Legal values for argument attr are those denoted by the DW_AT_* constants in the DWARF
     specification.

     Argument atp points to a location into which the returned attribute descriptor will be written.  The returned descriptor may then be passed
     to the form query functions in the dwarf(3) API set to access the data associated with the attribute.

     If argument err is non-NULL, it will be used to return an error descriptor in case of an error.

RETURN VALUES

     Function dwarf_attr() returns DW_DLV_OK on success.

     If the debugging information entry descriptor denoted by argument die does not contain the named attribute, the function returns
     DW_DLV_NO_ENTRY and sets argument err.  For other errors, it returns DW_DLV_ERROR and sets argument err.

ERRORS

     Function dwarf_attr() can fail with the following errors:

     [DW_DLE_ARGUMENT]	Either of arguments die or atp was NULL.

     [DW_DLE_NO_ENTRY]	Argument die had no attribute corresponding to the value in argument attr.
