Name:filename_lookup
Proto:int filename_lookup(int dfd, struct filename *name, unsigned flags, struct path *path, struct path *root)
Type:int
Parameter:
Type | Parameter | Name |
---|---|---|
int | dfd | |
struct filename * | name | |
unsigned | flags | |
struct path * | path | |
struct path * | root |
2332 | flags |= LOOKUP_ROOT |
2334 | set_nameidata( & nd, dfd, name) |
2336 | If Value for the false possibility is greater at compile time(retval == - ECHILD) Then retval = Returns 0 and nd will be valid on success; Retuns error, otherwise. |
2338 | If Value for the false possibility is greater at compile time(retval == - ESTALE) Then retval = Returns 0 and nd will be valid on success; Retuns error, otherwise. |
2341 | If Value is more likely to compile time(!retval) Then audit_inode(name, dentry, 0) |
2343 | restore_nameidata() |
2345 | Return retval |
