NAME
dwarf_add_AT_producer -- create and attach a DW_AT_producer attribute LIBRARY
DWARF Access Library (libdwarf, -ldwarf) SYNOPSIS
#include <libdwarf.h> Dwarf_P_Attribute dwarf_add_AT_producer(Dwarf_P_Die die, char *producer, Dwarf_Error *err); DESCRIPTION
Function dwarf_add_AT_producer() creates a DW_AT_producer attribute descriptor and attaches it to the debugging information entry referenced by argument die. The created attribute will have DWARF form DW_FORM_strp. Argument die should reference a debugging information entry allocated using dwarf_new_die(3). Argument producer should point to a NUL-terminated string which will become the value of the created attribute. 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_producer() returns the created attribute descriptor. In case of an error, function dwarf_add_AT_producer() returns DW_DLV_BADADDR and sets the argument err. ERRORS
Function dwarf_add_AT_producer() can fail with: [DW_DLE_ARGUMENT] Either of the arguments die or producer was NULL. [DW_DLE_MEMORY] An out of memory condition was encountered during the execution of the function. SEE ALSO
