Lib

Specifies the library where a sub or function can be found as part of a declaration

Syntax

Declare { Sub | Function } proc_name Lib "libname" [ Alias "symbol_name" ] ( arguments list ) As return_type
Extern "mangling" lib "libname"
declarative statements
end Extern
Type T
As Integer dummy
Declare Constructor Lib "libname" [ Alias "symbol_name" ] ( arguments list )
end Type

Description

In Sub or Function declarations, and also in class method declarations (including constructors and destructors), Lib indicates the library containing the function. Libraries specified in this way are linked in as if #Inclib "Libname" or -l libname had been used.

Lib can also be used with Extern ... End Extern Blocks to specifiy a Lib for all declarations inside.
