Hi all,

Am fairly new to the programming world, but am kind of struggling along. I have written a piece of code for a client program with has given me some errors that i just can't see when compiling. The errors listed are :

 client.c: In function `main':
  client.c:118: error: syntax error before '-' token
  client.c: At top level:
  client.c:132: error: conflicting types for `close_socket'
  sockets.c.h:40: error: previous declaration of `close_socket'
  client.c:133: error: parse error before '}' token

And i have also listed the program below. I hope that someone can point out the errors in my ways. Thanks in advance for looking.

hi,

Thanks have done that, think that the ; is a typo error. Now when i compile i get :


gcc -w stream_sockets.o client.c -o client
display_menu
get_selection
get_prog_ch
get_prog_cat
get_prog_sub
collect2: ld returned 1 exit status
*** Exit 1
Stop.

what is going on here ?

I would guess you call the ld system command from somewhere in your program and it returned with an error. But it's only a guess since there's no code posted to verify it.
