PROC_DOULONGVEC_MINM(9)                The proc filesystem                PROC_DOULONGVEC_MINM(9)



NAME
       proc_doulongvec_minmax - read a vector of long integers with min/max values

SYNOPSIS
       int proc_doulongvec_minmax(struct ctl_table * table, int write, void __user * buffer,
                                  size_t * lenp, loff_t * ppos);

ARGUMENTS
       table
           the sysctl table

       write
           TRUE if this is a write to the sysctl file

       buffer
           the user buffer

       lenp
           the size of the user buffer

       ppos
           file position

DESCRIPTION
       Reads/writes up to table->maxlen/sizeof(unsigned long) unsigned long values from/to the
       user buffer, treated as an ASCII string.

       This routine will ensure the values are within the range specified by table->extra1 (min)
       and table->extra2 (max).

       Returns 0 on success.
