# NAME

# LIBRARY

DWARF Access Library (libdwarf, -ldwarf)

# SYNOPSIS

`#include <libdwarf.h>`

Dwarf_P_Attribute
`dwarf_add_AT_string`(Dwarf_P_Debug dbg, Dwarf_P_Die die, Dwarf_Half attr, char *str, Dwarf_Error *err);

# DESCRIPTION

Function `dwarf_add_AT_string`() creates an attribute descriptor belonging to the ‘string’ class and attaches it to the debugging information entry referenced by argument die. The created attribute descriptor will have DWARF form `DW_FORM_strp`.

Argument dbg should reference a DWARF producer instance allocated using dwarf_producer_init(3) or dwarf_producer_init_b(3).

Argument die should reference a debugging information entry allocated using dwarf_new_die(3).

Argument attr should specify the attribute code for the created attribute descriptor.

Argument str should hold a pointer to a NUL-terminated string which will become the value of the created attribute descriptor.

If argument err is not NULL, it will be used to store error information in case of an error.

# RETURN VALUES

On success, function `dwarf_add_AT_string`() returns the created attribute descriptor. In case of an error, function `dwarf_add_AT_string`() returns `DW_DLV_BADADDR` and sets the argument err.

# ERRORS

Function `dwarf_add_AT_string`() can fail with:

[`DW_DLE_ARGUMENT`]
  One of the arguments dbg, die or str was NULL.
[`DW_DLE_MEMORY`]
  An out of memory condition was encountered during the execution of the function.
