# bitmap\_parselist\_user(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.
