[cffi-devel] Using the exec() family of functions

[Leslie P. Polzer]

Hi,

I have tried to use execv() from glibc in SBCL, but it's either
not compatible with SBCL for some reason or I'm not calling it
correctly.

Perhaps one of you guys can spot mistakes here:


CL-USER(2): (use-package :cffi)

T
CL-USER(3): (define-foreign-library libc (:unix "libc.so.6"))

LIBC
CL-USER(4): (use-foreign-library libc)

#<CFFI::FOREIGN-LIBRARY {B277599}>
CL-USER(7): (defcfun "execv" :int (path :string) (args :pointer))

EXECV
CL-USER(14): (execv "/bin/chmod" (null-pointer))
zsh: segmentation fault  rlwrap sbcl
