declaration/definition	declare function-library

Syntax

  declare function-library string-expression

Sets the default function library for any following external function definition that does not have an "in function-library" part. More than one declare function-library declaration can appear in a program. If more than one is used, each declare function-library declaration applies to the function definitions that follow until another declare function-library declaration is encountered. This is consistent with all OmniMark library calls.

The "in function-library" part of an external function can be omitted only if the definition is preceded by a declare function-library declaration. There is no "built-in" or "system-supplied" default external function library.
