BITMAP_PARSELIST_USE(9) Basic Kernel Library Functions BITMAP_PARSELIST_USE(9)
NAME
bitmap_parselist_user -
SYNOPSIS
int bitmap_parselist_user(const char __user * ubuf, unsigned int ulen, unsigned long * maskp, int nmaskbits);
ARGUMENTS
ubuf
pointer to user buffer containing string.
ulen
buffer size in bytes. If string is smaller than this then it must be terminated with a .
maskp
pointer to bitmap array that will contain result.
nmaskbits
size of bitmap, in bits.
DESCRIPTION
Wrapper for bitmap_parselist, providing it with user buffer.
We cannot have this as an inline function in bitmap.h because it needs linux/uaccess.h to get the access_ok declaration and this causes
cyclic dependencies.
