Also be careful to use NullS + and NOT to use 0, as on some machines 0 is not the same size as a + character pointer, or not the same bit pattern as NullS. +*/ + +#include "strings_def.h" + +char *strxmov(char *dst,const char *src, ...) +{ + va_list pvar; + + va_start(pvar,src); + while (src != NullS) { + while ((*dst++ = *src++)) ; + dst--; + src = va_arg(pvar, char *); + } + va_end(pvar); + *dst = 0; /* there might have been no sources! */ + return dst; +} |
