bitmap_parse_user(9)
NAME
bitmap_parse_user
SYNOPSIS
int bitmap_parse_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_parse, 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.
