Hi, could someone point out where I can find the the decimal values of EACCES, EEXIST, EIDRM, ENOENT, ENOMEM and ENOSPC for <sys/msg.h>. I made a program that returns error number 13, but I don't know what error correspond to 13. Thanks, Andre __________________________________ Do you Yahoo!? Yahoo!
