Name:Fetch a null-terminated string. Caller MUST set *(u32 *)dest with max* length and relative data location.
Proto:static inline __attribute__((__always_inline__)) int fetch_store_string(unsigned long addr, void *dest, void *base)
Type:int
Parameter:
Type | Parameter | Name |
---|---|---|
unsigned long | addr | |
void * | dest | |
void * | base |
153 | maxlen = get_loc_len(loc) |
154 | dst = get_loc_data(dest, base) |
157 | If Value for the false possibility is greater at compile time(!maxlen) Then Return -ENOMEM |
160 | If addr == FETCH_TOKEN_COMM Then ret = Copy a NUL terminated string into a sized buffer |
162 | Else ret = Copy a NUL terminated string from userspace |
164 | If ret >= 0 Then |
177 | Return ret |
