Glossary of Errors
controls whether eld considers unresolved references to be errors, warnings, or
neither.
User library. A user library is a DLL. A program is allowed to specify at most one
user library that it will need at runtime, and the user library is specified by storing its
Guardian filename within the program, through the -set libname option of eld,
rather than by telling eld to use a DLL the usual way, such as by a -l option.
Variable data. This refers to data that can be modified after the process has started
running. This is different from data that is constant, or that contains addresses that
may need to be modified when the process begins running but cannot be modified
thereafter.
Workfile. eld first creates workfiles for its output files, and only at the end does it
rename the workfiles to the final output filenames.
Write. If an error occurs when writing a file, it may indicate that there is no space left
on that disk.
Zimpimp file. This is a special type of import library that represents all the symbols
that exist in the system library.
