NAME

dwarf_get_relocation_info_count – return the number of relocation arrays

LIBRARY

DWARF Access Library (libdwarf, -ldwarf)

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.
