hi, 

 

I know that in µClinux, the standard system call "fork()" were replaced by "vfork()" 

 

I want to know why ? and what diference between them ?

sdhnain, 

 

fork() requires an MMU...uCLinux is for MMU-less processors. vfork() is similar to fork(), except that it blocks the parent. 

 

Just google "uCLinux fork" and you'll get plenty of useful results. 

 

Cheers,
