# 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.
