Name

proc_douintvec_minmax — read a vector of unsigned ints with min/max values

Synopsis

int proc_douintvec_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 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.
