He. This is _not_quite_ correct. Not in U-Boot, and not in genreal. [But your comment asking for a negative return code is valid, of course.] Best regards, Wolfgang Denk -- DENX Software Engineering GmbH, MD: Wolfgang Denk & Detlev Zundel HRB 165235 Munich, Office: Kirchenstr.5, D-82194 Groebenzell, Germany Phone: (+49)-8142-66989-10 Fax: (+49)-8142-66989-80 Email: w...@denx.de Zero is an enigmatic value. It can mean success (fclose) or failure (scanf). It can mean black or white. It can mean no permissions (chmod) or all permissions (umask). It can mean now (setjmp) or later (atexit). It can mean the beginning (lseek) or the end (read). It can mean myself (getpgrp) or child (fork). It can mean all (kill's 1st argument) or nothing (kill's 2nd argument). It can mean `default' (SIG_IGN) or `I don't care' (waitpid) or `try to guess' (strtol). Indeed 0 lets you talk to God (setuid). Verily is 0 all things to all people. _______________________________________________ U-Boot mailing list U-Boot@lists.denx.de http://lists.denx.de/mailman/listinfo/u-boot
