-- FUNCTION NAME: CXB30131 ("combine_two_strings")
--
-- FUNCTION DESCRIPTION:
-- This C function returns a pointer to the combination of two
-- input strings.
--
-- INPUTS:
-- This function requires that two parameters be passed to it.
-- The type of both of these parameters are pointer to char (which
-- is used to reference an array of chars).
--
-- PROCESSING:
-- The function will create a char array that is equal to the combined
-- length of the char arrays referenced by the two input parameters.
-- The char elements contained in the char arrays specified by the
-- parameters will be combined (in order) into this new char array.
--
-- OUTPUTS:
-- The newly created char array will be returned as the function
-- result through the function name. The char arrays referenced by the
-- two parameters will be unaffected.
--
-- CHANGE HISTORY:
-- 12 Oct 95 SAIC Initial prerelease version.
-- 26 Oct 96 SAIC Modified temp array initialization.
-- 15 Feb 99 RLB Repaired to remove non-standard function strdup.
--!
