NAME
dwarf_add_AT_const_value_signedint,
dwarf_add_AT_const_value_string,
dwarf_add_AT_const_value_unsignedint —
create and attach a DW_AT_const_value attribute
LIBRARY
DWARF Access Library (libdwarf, -ldwarf)
SYNOPSIS
#include <libdwarf.h>
Dwarf_P_Attribute
dwarf_add_AT_const_value_signedint(
Dwarf_P_Die
die,
Dwarf_Signed value,
Dwarf_Error *err);
Dwarf_P_Attribute
dwarf_add_AT_const_value_string(
Dwarf_P_Die
die,
char *str,
Dwarf_Error
*err);
Dwarf_P_Attribute
dwarf_add_AT_const_value_unsignedint(
Dwarf_P_Die
die,
Dwarf_Unsigned value,
Dwarf_Error *err);
DESCRIPTION
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.
RETURN VALUES
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.
ERRORS
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.
