Programming

Hello everybody !

I have a first program, called "server" which build 2 FIFO's in this way:

Code:

...
#define PERMS 0666
#define FIFO1 "\tmp\cerere"
#define FIFO2 "\tmp\raspuns"
...
mkfifo(FIFO1, PERMS)
mkfifo(FIFO2, PERMS)
...

I want to access these FIFO's in a second separate program, called "client".
I tried to pass the FIFO's path in the client command line, like that:
but when I tried to open the FIFO's the results were only "Error: No such file or directory."

This is how I transform the command line arguments in "client":

Code:

...
const char* FIFO1 = malloc(sizeof (argv[1]));
strncpy(FIFO1, argv[1], strlen(argv[1]));
const char* FIFO2 = malloc(sizeof (argv[2]));
strncpy(FIFO2, argv[2], strlen(argv[2]));
...

I tried another ways to pass the FIFO's path in the client command line, like that:
I received same error.

If I defined directly the FIFO's path in the source code of "client", like that:

Code:

#define FIFO1 "\tmp\cerere"
#define FIFO2 "\tmp\raspuns"

the "client" works fine.

What is wrong ? May somebody help me ?
Thank you !

One error:

Code:

// this should be
const char* FIFO1 = malloc(strlen (argv[1]));
strncpy(FIFO1, argv[1], strlen(argv[1]));
const char* FIFO2 = malloc(strlen (argv[2]));
strncpy(FIFO2, argv[2], strlen(argv[2]));
