PROC_DOULONGVEC_MS_J(9) The proc filesystem PROC_DOULONGVEC_MS_J(9)

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.
