Sh DESCRIPTION
These convenience functions are used to retrieve DWARF attribute
values associated with a Debugging Information Entry (DIE) descriptor
denoted by argument
Fa die .
These functions store the value of the requested attribute into the
location pointed to by their second argument, provided that the requested
attribute exists in the debugging information entry.
Pp
The list of functions and the DWARF attribute that they retrieve are:
Pp
Bl -tag -width ".Fn dwarf_arrayorder" -compact
It Fn dwarf_arrayorder
Retrieve the
Dv DW_AT_ordering
attribute value.
It Fn dwarf_bitoffset
Retrieve the
Dv DW_AT_bit_offset
attribute value.
It Fn dwarf_bitsize
Retrieve the
Dv DW_AT_bit_size
attribute value.
It Fn dwarf_bytesize
Retrieve the
Dv DW_AT_byte_size
attribute value.
It Fn dwarf_highpc
Retrieve the
Dv DW_AT_high_pc
attribute value.
It Fn dwarf_highpc_b
Retrieve the
Dv DW_AT_high_pc
attribute value.
It Fn dwarf_lowpc
Retrieve the
Dv DW_AT_low_pc
attribute value.
It Fn dwarf_srclang
Retrieve the
Dv DW_AT_language
attribute value.
El
Pp
Function
Fn dwarf_highpc_b
is an enhanced version of function
Fn dwarf_highpc .
It sets the location specified by argument
Fa ret_form
to the form code of the attribute
Dv DW_AT_high_pc ,
and sets the location specified by argument
Fa ret_class
to the class of that form.
A value of
Dv NULL
may be used for either of the arguments
Fa ret_form
or
Fa ret_class
if the caller is not interested in the respective value.
Sh RETURN VALUES
These functions return
Dv DW_DLV_OK
on success.
Pp
If the debugging information entry descriptor denoted by argument
Fa die
does not contain the requested attribute, these functions return
Dv DW_DLV_NO_ENTRY
and set argument
Fa err .
For other errors, they return
Dv DW_DLV_ERROR
and set argument
Fa err .
Sh ERRORS
These functions can fail with the following errors:
Bl -tag -width ".Bq Er DW_DLE_ARGUMENT"
It Bq Er DW_DLE_ARGUMENT
Arguments
Fa die ,
Fa ret_highpc ,
Fa ret_lowpc ,
Fa ret_size ,
Fa ret_lang
or
Fa ret_order
were
Dv NULL .
It Bq Er DW_DLE_NO_ENTRY
Argument
Fa die
had no requested attribute.
