  IMPORT

   IMPORT <function[(<type> <arg1>[, <type> <arg2>][, ...])]> FROM <library> TYPE
   <type> [ALIAS word]

   Type: statement

   Imports a function from a C library defining the type of returnvalue.
   Optionally, the type of arguments can be specified. Also optionally it
   is possible to define an alias under which the imported function will be
   known to BaCon. Examples:

   IMPORT "ioctl" FROM "libc.so" TYPE int
   IMPORT "gdk_draw_line(long, long, int, int, int, int)" FROM
   "libgdk-x11-2.0.so" TYPE void
   IMPORT "fork" FROM "libc.so" TYPE int ALIAS "FORK"
   IMPORT "atan(double)" FROM "libm.so" TYPE double ALIAS "arctangens"
