The argument - list is terminated by the first NULL pointer encountered. Pointers - to empty strings are ignored. - -NOTES - - This function uses xmalloc() which is expected to be a front end - function to malloc() that deals with low memory situations. In - typical use, if malloc() returns NULL then xmalloc() diverts to an - error handler routine which never returns, and thus xmalloc will - never return a NULL pointer. If the client application wishes to - deal with low memory situations itself, it should supply an xmalloc - that just directly invokes malloc and blindly returns whatever - malloc returns. -*/ - - -#include "ansidecl.h" -#include "libiberty.h" - -#ifdef ANSI_PROTOTYPES -#include <stdarg.h> -#else -#include <varargs.h> -#endif - -#ifdef __STDC__ -#include <stddef.h> -extern size_t strlen (const char *s); -#else -extern int strlen (); -#endif - -#define NULLP (char *)0 - -/* VARARGS */ -#ifdef ANSI_PROTOTYPES -char * -concat (const char *first, ...) -#else -char * -concat (va_alist) - va_dcl -#endif -{ - register int length; - register char *newstr; - register char *end; - register const char *arg; - va_list args; -#ifndef ANSI_PROTOTYPES - const char *first; -#endif - - /* First compute the size of the result and get sufficient memory. */ - -#ifdef ANSI_PROTOTYPES - va_start (args, first); -#else - va_start (args); - first = va_arg (args, const char *); -#endif - - if (first == NULLP) - length = 0; - else - { - length = strlen (first); - while ((arg = va_arg (args, const char *)) != NULLP) - { - length += strlen (arg); - } - } - newstr = (char *) xmalloc (length + 1); - va_end (args); - - /* Now copy the individual pieces to the result string. */ - - if (newstr != NULLP) - { -#ifdef ANSI_PROTOTYPES - va_start (args, first); -#else - va_start (args); - first = va_arg (args, const char *); -#endif - end = newstr; - if (first != NULLP) - { - arg = first; - while (*arg) - { - *end++ = *arg++; - } - while ((arg = va_arg (args, const char *)) != NULLP) - { - while (*arg) - { - *end++ = *arg++; - } - } - } - *end = '\000'; - va_end (args); - } - - return (newstr); -} - -#ifdef MAIN - -/* Simple little test driver. */ - -#include <stdio.h> - -int -main () -{ - printf ("\"\" = \"%s\"\n", concat (NULLP)); - printf ("\"a\" = \"%s\"\n", concat ("a", NULLP)); - printf ("\"ab\" = \"%s\"\n", concat ("a", "b", NULLP)); - printf ("\"abc\" = \"%s\"\n", concat ("a", "b", "c", NULLP)); - printf ("\"abcd\" = \"%s\"\n", concat ("ab", "cd", NULLP)); - printf ("\"abcde\" = \"%s\"\n", concat ("ab", "c", "de", NULLP)); - printf ("\"abcdef\" = \"%s\"\n", concat ("", "a", "", "bcd", "ef", NULLP)); - return 0; -} - -#endif |
