Time for my 2cents. The above only fixes part of the problem and can
return a buffer without and NL to the caller. The "specifications" don't
say if the caller must handle this.
char *GetLine(int Socket){
static char Buffer[4096];
int rc = 0;
int offset = 0;
while (rc >= 0 && offset < sizeof(Buffer)){
rc = recv (Socket, Buffer + offset, sizeof (Buffer) - offset,
0);
if (rc > 0) {
if ( '\n' == Buffer[offset+rc-1] )
return Buffer;
else
offset += rc;
}
}
return NULL; /* No NL or recv failed */
}
What's left is to decide how many times we allow recv to return no data
before giving up.
