40 * kernctl_syscall_mask - Get syscall mask associated to a channel FD.
41 *
42 * The parameter @syscall_mask should initially be either NULL or point
43 * to memory allocated with malloc(3) or realloc(3). When the function
44 * returns, it will point to a memory area of the size required for the
45 * bitmask (using realloc(3) to resize the memory).
46 *
47 * It returns 0 if OK, -1 on error. In all cases (error and OK),
48 * @syscall_mask should be freed by the caller with free(3).
