Check if we even have a parameter before checking its value. Running this command without any arguments may not make a lot of sense, but reacting with a segmentation fault is unduly harsh. While we're at it, avoid casting argv by declaring it const right away. Signed-off-by: Rene Scharfe <redacted> --- test-subprocess.c | 6 +++--- 1 file changed, 3 insertions(+), 3 deletions(-)
