These functions create a
DW_AT_const_value
attribute descriptor and attach it to the debugging information entry
referenced by argument
die.
Argument
die should reference a debugging
information entry allocated using
dwarf_new_die(3).
Function
dwarf_add_AT_const_value_signedint()
creates a
DW_AT_const_value
attribute
descriptor containing the signed value specified by argument
value. The created attribute descriptor will
have DWARF form
DW_FORM_sdata
.
Function
dwarf_add_AT_const_value_unsignedint()
creates a
DW_AT_const_value
attribute
descriptor containing the unsigned value specified by argument
value. The created attribute descriptor will
have DWARF form
DW_FORM_udata
.
Function
dwarf_add_AT_const_value_string() creates
a
DW_AT_const_value
attribute descriptor
containing the string pointed to by the NUL-terminated argument
str. The created attribute descriptor will
have DWARF form
DW_FORM_strp
.
If argument
err is not NULL, it will be used by
these functions to store error information in case of an error.
On success, these functions return the created attribute descriptor. In case of
an error, these functions return
DW_DLV_BADADDR
and set the argument
err.
These functions can fail with:
-
-
- [
DW_DLE_ARGUMENT
]
- Either of the arguments
die or
str was NULL.
-
-
- [
DW_DLE_MEMORY
]
- An out of memory condition was encountered during
execution.
