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.
