Re: [C400-L] basic C question







You have forgotten the a main () clause. The compiler needs to know where
to start the program, it's not as simple as other languages where the
program starts at the first line. ;-)
Most likelly you'll wan't to return the result of you computation also.

Pardon my ignorance. I just can't seems to be able to figure out why
this will not compile:

#include <string.h>
#include <unistd.h>

char hostName[256];
int hostNameLen;

hostNameLen = sizeof(hostName);

gethostname(hostName, hostNameLen);

exit(0);




Below is portion of the compiler error:
4 |

5 | char hostName[256];

6 | int hostNameLen;

7 |

8 | hostNameLen = sizeof(hostName);

===========>
.a......................................................................
