fork and vfork??

[albtross]

what's the difference between fork and vfork?

[teknomage1]

From the man page:

DESCRIPTION
The vfork() function shall be equivalent to fork(), except that the behavior is undefined
if the process created by vfork() either modifies any data other than a variable of type
pid_t used to store the return value from vfork(), or returns from the function in which
vfork() was called, or calls any other function before successfully calling _exit() or one
of the exec family of functions.
