Function Documentation

db_argv_to_dpv()

struct directory ** db_argv_to_dpv ( const struct db_i *  dbip, const char **  argv  )

extern

convert an argv list of names to a directory pointer array.

If db_lookup fails for any individual argv, an empty directory structure is created and assigned the name and RT_DIR_PHONY_ADDR

The returned directory ** structure is NULL terminated.

db_dpv_to_argv()

char ** db_dpv_to_argv ( struct directory **  dpv )

extern

convert a directory pointer array to an argv char pointer array.
