    PUTENV_FUNC putenv_cb, ITERENV_FUNC iterenv_cb);
```

## ARGUMENTS

data - user data to be passed to the specified callbacks\
 read\_cb - a cb to replace fread(stdin)\
 writef\_cb - a cb to repalce fprintf(stdout)\
 write\_cb - a cb to replace fwrite(stdout)\
 getenv\_cb - a cb to replace getenv\
 putenv\_cb - a cb to replace putenv\
 iterenv\_cb - a cb to replace the default environment iteration\
