DWARF_TRANSFORM_TO_DISK_FORM(3) FreeBSD Library Functions Manual
NAME
dwarf_transform_to_disk_form - transform DWARF information into byte
streams
LIBRARY
DWARF Access Library (libdwarf, -ldwarf)
SYNOPSIS
#include <libdwarf.h>
Dwarf_Signed
dwarf_transform_to_disk_form(Dwarf_P_Debug dbg, Dwarf_Error *err);
DESCRIPTION
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.
