Steering file command summary
A summary of the commands you can use in a steering file.
Steering file commands enable you to:
Manage symbols in the symbol table.
Control the copying of symbols from the static symbol table to the dynamic symbol table.
Store information about the libraries that a link unit depends on.
For example, you can use steering files to protect intellectual property, or avoid namespace clashes.
The steering file commands are:
|EXPORT||Specifies that a symbol can be accessed by other shared objects or executables.|
|HIDE||Makes defined global symbols in the symbol table anonymous.|
|IMPORT||Specifies that a symbol is defined in a shared object at runtime.|
|RENAME||Renames defined and undefined global symbol names.|
|REQUIRE||Creates a DT_NEEDED tag in the dynamic array. DT_NEEDED tags specify dependencies to other shared objects used by the application, for example, a shared library.|
|RESOLVE||Matches specific undefined references to a defined global symbol.|
|SHOW||Makes global symbols visible. This command is useful if you want to make a specific symbol visible that is hidden using a HIDE command with a wildcard.|
The steering file commands control only global symbols. Local symbols are not affected by any of these commands.
