/* -- CXB30131.C -- -- Grant of Unlimited Rights -- -- Under contracts F33600-87-D-0337, F33600-84-D-0280, MDA903-79-C-0687, -- F08630-91-C-0015, and DCA100-97-D-0025, the U.S. Government obtained -- unlimited rights in the software and documentation contained herein. -- Unlimited rights are defined in DFAR 252.227-7013(a)(19). By making -- this public release, the Government intends to confer upon all -- recipients unlimited rights equal to those held by the Government. -- These rights include rights to use, duplicate, release or disclose the -- released technical data and computer software in whole or in part, in -- any manner and for any purpose whatsoever, and to have or permit others -- to do so. -- -- DISCLAIMER -- -- ALL MATERIALS OR INFORMATION HEREIN RELEASED, MADE AVAILABLE OR -- DISCLOSED ARE AS IS. THE GOVERNMENT MAKES NO EXPRESS OR IMPLIED -- WARRANTY AS TO ANY MATTER WHATSOEVER, INCLUDING THE CONDITIONS OF THE -- SOFTWARE, DOCUMENTATION OR OTHER INFORMATION RELEASED, MADE AVAILABLE -- OR DISCLOSED, OR THE OWNERSHIP, MERCHANTABILITY, OR FITNESS FOR A -- PARTICULAR PURPOSE OF SAID MATERIAL. --* -- -- 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. --! */ #include <string.h> #include <stdlib.h> char *stringdup (char *s) { char *result = malloc(sizeof(char)*(strlen(s)+1)); return strcpy(result,s); } char *CXB30131 (char *string1, char *string2) /* NOTE: The above function definition should be accepted by an ANSI-C */ /* compiler.
