dwarf_get_relocation_info_count(3)

NAME

dwarf_get_relocation_info_count – return the number of relocation arrays

LIBRARY

library “libdwarf”

SYNOPSIS

#include <libdwarf.h>

int

dwarf_get_relocation_info_count(Dwarf_P_Debug dbg, Dwarf_Unsigned *reloc_cnt, int *drd_buffer_version, Dwarf_Error *err);

DESCRIPTION

Function dwarf_get_relocation_info_count() retrieves the total number of relocation arrays generated by a prior call to dwarf_transform_to_disk_form(3).

Argument dbg should reference a DWARF producer instance allocated using dwarf_producer_init(3) or dwarf_producer_init_b(3). The DW_DLC_SYMBOLIC_RELOCATIONS flag should have been set on the producer instance.

Argument reloc_cnt should point to a location which will be set to the total number of relocation arrays generated.

Argument drd_buffer_version should point to a location which will be set to the version number of the relocation structures returned (see the symbol DWARF_DRD_BUFFER_VERSION, defined in the header file ⟨libdwarf.h⟩).

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_get_relocation_info_count() returns DW_DLV_OK. It returns DW_DLV_NO_ENTRY if the DW_DLC_SYMBOLIC_RELOCATIONS flag is not set on the producer instance. In case of an error, function dwarf_get_relocation_info_count() returns DW_DLV_ERROR and sets the argument err.

ERRORS

Function dwarf_get_relocation_info_count() can fail with:

[DW_DLE_ARGUMENT]: One of the arguments dbg, reloc_cnt or drd_buffer_version was NULL.
[DW_DLE_NO_ENTRY]: The DW_DLC_SYMBOLIC_RELOCATIONS flag was not set.
