Top Forums Programming Determining free(available) memory in MV linux Post 98935 by trancedeejay on Monday 13th of February 2006 05:31:34 AM

I've noticed that meminfo does not display real values - function free -m does. If I insert to memtester the same value that I got from free -m memtester works normally, but when I put only 1MB higher number memtester terminates - not enough memory(so that means the function in shell free -m displays real free memory data). Question now is how to enter the shell function from C to save and display data from free -m?

NAME
wall -- write a message to users SYNOPSIS
wall [-n] [-t TIMEOUT] [file] DESCRIPTION
Wall displays the contents of file or, by default, its standard input, on the terminals of all currently logged in users. The command will cut over 79 character long lines to new lines. Short lines are white space padded to have 79 characters. The command will always put carriage return and new line at the end of each line. Only the super-user can write on the terminals of users who have chosen to deny messages or are using a program which automatically denies messages. Reading from a file is refused when the invoker is not superuser and the program is suid or sgid. OPTIONS
-n, --nobanner Supress banner -t, --timeout TIMEOUT Write timeout to terminals in seconds. Argument must be positive integer. Default value is 300 seconds, which is a legacy from time when people ran terminals over modem lines. -V, --version Output version and exit. -h, --help Output help and exit. SEE ALSO
mesg(1), talk(1), write(1), shutdown(8) HISTORY
A wall command appeared in Version 7 AT&T UNIX. AVAILABILITY
