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.
