NAME¶
proc_doulongvec_ms_jiffies_minmax - read a vector of millisecond values with min/max values
SYNOPSIS¶
int proc_doulongvec_ms_jiffies_minmax(struct ctl_table * table, int write, void __user * buffer, size_t * lenp, loff_t * ppos);
ARGUMENTS¶
struct ctl_table * table
the sysctl table
int write
TRUE if this is a write to the sysctl file
void __user * buffer
the user buffer
size_t * lenp
the size of the user buffer
loff_t * 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. The values are treated as milliseconds, and converted to jiffies when they are stored.
This routine will ensure the values are within the range specified by table->extra1 (min) and table->extra2 (max).
Returns 0 on success.
