readclose_append

#include <readclose.h>

ssize_t readclose_append(int fd,stralloc* sa,
size_t bufsize);

readclose_append reads the whole content into the stralloc sa, appending it to the existing content. The file is read in chunks of bufsize bytes size. If everything worked fine, readclose_append returns 0. On error, readclose_append returns -1 and sets errno appropriately.
