ok. The environment is WinNT SP4. Here is the failing code :

------------------
char    chaine[50];
int        fd2;
int        res;

fd2 = open("C:/temp/toto.txt", O_RDONLY, 0);
 printf("\n--- test de read() ---\n");
 strcpy(chaine, "");
 res = read(fd2, chaine, 10);
 if (res == -1) perror("erreur sur read");
 fprintf(stdout, "%d octets ont ete lus par read()\n", res);
 printf("chaine = %s\n", chaine);
-------------------

Note that file c`\temp\toto.txt exists and is a regular ASCII text file.

read always returns -1.
