Description
A stream opened by %popen() must be closed by %pclose(). The stream is closed automatically at FlashBASIC program termination.
Example(s)
include dm,bp,includes sysid.inc cfunction unix.builtin char buffer[128] if system(38)<sys$imp> = sys$win then cmd = "dir" end else cmd = "ls -l" end ptr=(char*)%popen(cmd,"r") if ptr=0 then crt "error" ; stop loop n=(char*)%fgets(buffer,128,(char*)ptr) while n # 0 do print field(buffer,char(0),1) repeat %pclose((char*)ptr) |
This example executes a UNIX command, capturing the result.
