proc_douintvec_minmax — read a vector of unsigned ints with min/max values
int proc_douintvec_minmax ( | struct ctl_table * table, |
int write, | |
void __user * buffer, | |
size_t * lenp, | |
loff_t * ppos) ; |
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
Reads/writes up to table->maxlen/sizeof(unsigned int) unsigned integer values from/to the user buffer, treated as an ASCII string. Negative strings are not allowed.
This routine will ensure the values are within the range specified by table->extra1 (min) and table->extra2 (max). There is a final sanity check for UINT_MAX to avoid having to support wrap around uses from userspace.
Returns 0 on success.
