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
           \0.

       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.
