Man page 9 : proc_dointvec_ms_jiffies

proc_dointvec_ms_jiffies - read a vector of integers as 1 milliseconds

int proc_dointvec_ms_jiffies(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
    the current position in the file

Reads/writes up to table->maxlen/sizeof(unsigned int) integer values from/to the user buffer, treated as an ASCII string. The values read are assumed to be in 1/1000 seconds, and are converted into jiffies.

Returns 0 on success.
