fsutil_append()

void fsutil_append

(

char **

argv

)

Copies file FILE_NAME from the file system to the scratch device, in ustar format.

filesys/fsutil.h

The first call to this function will write starting at the beginning of the scratch device. Later calls advance across the device. This position is independent of that used for fsutil_extract(), so ‘extract’ should precede all `append's.
