BITMAP_PARSE_USER(9) Basic Kernel Library Functions BITMAP_PARSE_USER(9)
NAME
bitmap_parse_user - convert an ASCII hex string in a user buffer into a bitmap
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 .
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.
