DWARF_FORMSTRING(3)					   BSD Library Functions Manual 				       DWARF_FORMSTRING(3)

NAME

     dwarf_formstring -- return the value of a STRING class attribute

LIBRARY

     DWARF Access Library (libdwarf, -ldwarf)

SYNOPSIS

     #include <libdwarf.h>

     int
     dwarf_formstring(Dwarf_Attribute attr, char **ret, Dwarf_Error *err);

DESCRIPTION

     Function dwarf_formstring() sets the location pointed to by argument ret to a pointer to a NUL-terminated string containing the value of the
     attribute referenced by argument attr.  The form of argument attr must be one of DW_FORM_string or DW_FORM_strp.

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

   Memory Management
     The memory area referenced by the returned pointer is managed by the DWARF(3) library.  The application should not attempt to directly free
     this memory area.

RETURN VALUES

     Function dwarf_formstring() returns DW_DLV_OK on success.	In case of an error, it returns DW_DLV_ERROR and sets argument err.

ERRORS

     Function dwarf_formstring() may fail with the following errors:

     [DW_DLE_ARGUMENT]	     Either of arguments attr or ret was NULL.

     [DW_DLE_ATTR_FORM_BAD]  The attribute referenced by argument attr was not of a permitted kind.

DWARF_FORMUDATA(3)					   BSD Library Functions Manual 					DWARF_FORMUDATA(3)

NAME

     dwarf_formudata, dwarf_formsdata -- return the value of a CONSTANT class attribute

LIBRARY

     DWARF Access Library (libdwarf, -ldwarf)

SYNOPSIS

     #include <libdwarf.h>

     int
     dwarf_formudata(Dwarf_Attribute attr, Dwarf_Unsigned *ret, Dwarf_Error *err);

     int
     dwarf_formsdata(Dwarf_Attribute attr, Dwarf_Signed *ret, Dwarf_Error *err);

DESCRIPTION

     These functions return the value associated with a DWARF attribute describing a constant.

     Function dwarf_formudata() sets the location pointed to by argument ret to the value of the attribute referenced by argument attr, treating
     the value as an unsigned quantity.  Argument attr must have one of the following forms: DW_FORM_data1, DW_FORM_data2, DW_FORM_data4,
     DW_FORM_data8 and DW_FORM_udata.

     Function dwarf_formsdata() sets the location pointed to by argument ret to the value of the attribute referenced by argument attr, appropri-
     ately sign extended.  Argument attr must have one of the following forms: DW_FORM_data1, DW_FORM_data2, DW_FORM_data4, DW_FORM_data8 and
     DW_FORM_sdata.

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

RETURN VALUES

     These functions return DW_DLV_OK on success.  In case of an error, they return DW_DLV_ERROR and set argument err.

ERRORS

     These functions may fail with the following errors:

     [DW_DLE_ARGUMENT]	     Either of arguments attr or ret was NULL.

     [DW_DLE_ATTR_FORM_BAD]  The attribute referenced by argument attr was not of a permitted kind.
