Could someone tell me why one must use vfork() if one is to call exec right

under stand why before trying vfork()
Thanks,

vfork() is not thread safe and you should not use it. fork() and
vfork() return twice, once for the parent and once for the child
process, the difference is that vfork does not clone the address space
of the parent process. Solaris unlike linux will fail if there is not
enough memory to host both the parent and the child address space.
