| -- 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. |
