A slight correction, the pragma is part of the package specification which contains the function.
For example
CREATE OR REPLACE PACKAGE REMEDY IS

     FUNCTION SLAC_DATE(ELAPSED_SECONDS IN NUMBER) RETURN DATE ;
     PRAGMA RESTRICT_REFERENCES(SLAC_DATE,WNDS, RNDS, TRUST);

END REMEDY;
/

The "TRUST" argument was not introduced until 8i and means that you trust other functions called by the functions not to violate the pragma.

You need in the stored procedure this stmt:

pragma restrict_references (<name of function>, WNDS [, WNPS] [, RNDS] [, RNPS]); where:

WNDS means "writes no database state" (does not modify database tables)

WNPS means "writes no package state" (does not change the values of
packaged variables)

RNDS means "reads no database state" (does not query database tables)

RNPS means "reads no package state" (does not reference the values of
packaged variables)

Regards.

PS:This is since 7.X.
