dwarf_transform_to_disk_form3

Usage

Library

library “libdwarf”

Overview

Function dwarf_transform_to_disk_form() transforms the DWARF information gathered by the producer into byte streams for the application to write out as ELF sections. If the flag DW_DLC_SYMBOLIC_RELOCATIONS is set on the producer, the function will also generate the associated relocation arrays.

Argument dbg should reference a DWARF producer instance allocated using dwarf_producer_init(3) or dwarf_producer_init_b(3).

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

After a call to this function, the application can call the function dwarf_get_section_bytes(3) to retrieve the byte streams for each ELF section. If the flag DW_DLC_SYMBOLIC_RELOCATIONS was set on the descriptor, the application can also call the function dwarf_get_relocation_info(3) to retrieve the generated relocation arrays.

Return values

On success, function dwarf_transform_to_disk_form() returns the total number of ELF sections generated. In case of an error, function dwarf_transform_to_disk_form() returns DW_DLV_NOCOUNT and sets the argument err.

Errors

Function dwarf_transform_to_disk_form() can fail with:

[DW_DLE_ARGUMENT]

Argument dbg was NULL.

[DW_DLE_MEMORY]

An out of memory condition was encountered during execution.
