recv() not workin fine.....
hi !
In my program I have a structure as shown below:
struct data
{
int a;
char *b;
long c;
}str;
i have assigned the following values to it:
strcpy(str.b,"John");
str.a=10;
str.c=123435;
The client is tryin to send struct data to the server using
send(sock,(char * )&str,sizeof(str),flag);
At the server side the data is read using the following:
recv(sock,(char *)&str,sizeof(str),flag);
but when i print the values on to the screen only the values of a and c get printed and b does not get printed.
The server also contains the structure.
i cant figure out y this is happening. any help is appreciated.
thanx

hi,
the syntax of recv function is:
int recv( int sockfd, void *buffer, int length, unsigned int flags);
Suppose i declared a buffer of size 100 ,then length to be specified in recv function is sizeof(buffer) or sizeof(buffer)-1 ( i.e 100 or 99)
thanks in advance (2 Replies)

mvwinstr
curs_instr(3X) curs_instr(3X)
NAME
instr, innstr, winstr, winnstr, mvinstr, mvinnstr, mvwinstr, mvwinnstr - get a string of characters from a curses window
SYNOPSIS
#include <curses.h>
int instr(char *str);
int innstr(char *str, int n);
int winstr(WINDOW *win, char *str);
int winnstr(WINDOW *win, char *str, int n);
int mvinstr(int y, int x, char *str);
int mvinnstr(int y, int x, char *str, int n);
int mvwinstr(WINDOW *win, int y, int x, char *str);
int mvwinnstr(WINDOW *win, int y, int x, char *str, int n);
DESCRIPTION
These routines return a string of characters in str, extracted starting at the current cursor position in the named window. Attributes are
stripped from the characters. The four functions with n as the last argument return a leading substring at most n characters long (exclu-
sive of the trailing NUL).
RETURN VALUE
All of the functions return ERR upon failure, or the number of characters actually read into the string.
X/Open defines no error conditions. In this implementation, if the window parameter is null or the str parameter is null, a zero is
returned.
NOTES
Note that all routines except winnstr may be macros.
PORTABILITY
SVr4 does not document whether a length limit includes or excludes the trailing NUL.
The ncurses library extends the XSI description by allowing a negative value for n. In this case, the functions return the string ending
at the right margin.
