27 -- 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.
