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.
