How to copy!

Original - C Code #include <stdio.h> int copy(const char* srcname, const char* dstname) { /* declare file pointers, and buffer char */ FILE *src, *dst; char buff; /* open files */ if(!(src = fopen(srcname, "rb"))) /* open for read, binary */ return -1; if(!(dst = fopen(dstname, "wb"))) /* open for write, binary */ { fclose(src); return -1; } /* read byte from src, and write to destination */ while(fread(&buff, sizeof(char), 1, src)) if(!fwrite(&buff, sizeof(char), 1, dst)) { fclose(src); fclose(dst); return -1; } /* return succes */ return 0; } int main(int argc, char **argv) { /* check if all parameters are there */ if(argc < 3) { printf("Not enough paramters.\n Correct usage: %s <source> <destination>\n", argv[0]); return -1; } /* copy files */ if(copy(argv[1], argv[2])) { printf("Copying failed"); return -1; } /* return succes */ return 0; }
