GETPROCMEM(integer-expression)

Returns the memory usage in bytes of a running process. The parameter is an index in the range 0 to GETPROCCOUNT - 1, identifying one of the active processes.

Examples

REM Print memory usage of all running processes
FOR i = 0 TO GETPROCCOUNT - 1
    PRINT "Process "; i; " uses "; GETPROCMEM(i); " bytes"
NEXT

REM Check if a process exceeds a memory limit
idx = 2
mem = GETPROCMEM(idx)
IF mem > 1048576 THEN
    PRINT "Process "; idx; " exceeds 1 MB"
ENDIF

REM Sum total memory of all processes
total = 0
FOR i = 0 TO GETPROCCOUNT - 1
    total = total + GETPROCMEM(i)
NEXT
PRINT "Total memory used by all processes = "; total; " bytes"

Notes

Returned value is in bytes, as a Retro Rocket BASIC integer.
Memory usage reflects the process’s working set at the time of the call; it may change dynamically as the process allocates or frees memory.
Passing an index outside 0 … GETPROCCOUNT - 1 raises an error.
Use alongside GETPROCID or GETPROCNAME$ to relate memory use to specific processes.
