The EXPORT command specifies that a symbol can be accessed by other shared objects or executables.
Note
A symbol can be exported only if the reference has STV_DEFAULT visibility.
You must use the --override_visibility command-line
option to enable the linker to override symbol visibility to STV_DEFAULT.

where:
patternIs a string, optionally including wildcard characters (either
*or?), that matches zero or more defined global symbols. IfpatternIf the symbol is not defined, the linker issues:
Warning: L6331W: No eligible global symbol matches pattern symbol
replacement_patternIs a string, optionally including wildcard characters (either
*or?), to which the defined global symbol is to be renamed. Wild characters must have a corresponding wildcard inpatternreplacement_patternpatternFor example:
EXPORT my_func AS func1renames and exports the defined symbol
my_funcasfunc1.
You cannot export a symbol to a name that already exists.
Only one wildcard character (either * or ?)
is permitted in EXPORT.
The defined global symbol is included in the dynamic symbol
table (as replacement_patternpattern
