Accessing Archived Functions From Your Code

Programs that call a library routine must use the assembler's
directive to specify the routine's start label as an external label. When link-
ing the program, specify one or more library files (
along with the names of the object files (
searches the library files to resolve symbols and links the appropriate rou-
tines into the executable file.
Any file containing a label referenced by your program is linked into the
executable output file. Linking libraries is faster than using individual
object files, and you do not have to enter all the file names, just the library
name.
In the following example, the archiver creates the
taining the object files:
elfar -c filter.dlb taps.doj coeffs.doj go_input.doj
If you then run the linker with the following command line, the linker
links the object files
example,
ADSP-BF535.ldf
linker -DADSP-BF535 main.doj sum.doj filter.dlb -o main.dxe
Assuming that one or more library routines from
from one or more of the object files, the linker searches the library,
extracts the required routines, and links the routines into the executable.
