-- FUNCTION NAME: CXB30131 ("combine_two_strings")
|
28 |
|
|
--
|
29 |
|
|
-- FUNCTION DESCRIPTION:
|
30 |
|
|
-- This C function returns a pointer to the combination of two
|
31 |
|
|
-- input strings.
|
32 |
|
|
--
|
33 |
|
|
-- INPUTS:
|
34 |
|
|
-- This function requires that two parameters be passed to it.
|
35 |
|
|
-- The type of both of these parameters are pointer to char (which
|
36 |
|
|
-- is used to reference an array of chars).
|
37 |
|
|
--
|
38 |
|
|
-- PROCESSING:
|
39 |
|
|
-- The function will create a char array that is equal to the combined
|
40 |
|
|
-- length of the char arrays referenced by the two input parameters.
|
41 |
|
|
-- The char elements contained in the char arrays specified by the
|
42 |
|
|
-- parameters will be combined (in order) into this new char array.
|
43 |
|
|
--
|
44 |
|
|
-- OUTPUTS:
|
45 |
|
|
-- The newly created char array will be returned as the function
|
46 |
|
|
-- result through the function name. The char arrays referenced by the
|
47 |
|
|
-- two parameters will be unaffected.
|
48 |
|
|
--
|
49 |
|
|
-- CHANGE HISTORY:
|
50 |
|
|
-- 12 Oct 95 SAIC Initial prerelease version.
|
51 |
|
|
-- 26 Oct 96 SAIC Modified temp array initialization.
|
52 |
|
|
-- 15 Feb 99 RLB Repaired to remove non-standard function strdup.
