DESCRIPTION
Function elftc_bfd_find_target() locates a binary object descriptor
corresponding to the descriptor name in argument target_name. Binary
object descriptors encapsulate properties of an object format such as its
file representation, ELF class, and byte endianness.
Known descriptor names and their properties include:

Function elftc_bfd_target_byteorder() returns the ELF byte order
associated with target descriptor target.
Function elftc_bfd_target_class() returns the ELF class associated with
target descriptor target.
Function elftc_bfd_target_flavor() returns the object format associated
with target descriptor target. The known object formats are:
ETF_ELF An ELF object.
ETF_BINARY Raw binary.
ETF_IHEX An object encoded in Intel hex format.
ETF_NONE An unknown object format.
ETF_SREC An object encoded as S-records.
RETURN VALUES
Function elftc_bfd_find_target() returns a valid pointer to an opaque
binary target descriptor if successful, or NULL in case of an error.
Function elftc_bfd_target_byteorder() returns the ELF byte order
associated with the target descriptor; one of ELFDATA2MSB or ELFDATA2LSB.
Function elftc_bfd_target_class() returns the ELF class associated with
the target descriptor; one of ELFCLASS32 or ELFCLASS64.
Function elftc_bfd_target_machine() returns the ELF architecture
associated with the target descriptor.
Function elftc_bfd_target_flavor() returns one of ETF_BINARY, ETF_ELF,
ETF_IHEX or ETF_SREC if successful or ETF_NONE in case of error.
EXAMPLES
To return descriptor information associated with target name "elf64-big"
use:
struct Elftc_Bfd_Target *t;
if ((t = elftc_bfd_find_target("elf64-big")) == NULL)
errx(EXIT_FAILURE, "Cannot find target descriptor");
printf("Class: %s\n", elftc_bfd_target_class(t) == ELFCLASS32 ?
"ELFCLASS32" : "ELFCLASS64");
printf("Byteorder: %s\n",
elftc_bfd_target_byteorder(t) == ELFDATA2LSB ? "LSB" : "MSB");
printf("Flavor: %d\n", elftc_bfd_target_flavor(t));
