Fix for bug #7390

This fixes the usage of old readdir_r(). errno is 0 if readdir_r() is succesful. ---8<------------------------------------------------------------ RETURN VALUES Upon successful completion, readdir() and readdir_r() return a pointer to an object of type struct dirent. When an error is encountered, a null pointer is returned and errno is set to indicate the error. When the end of the directory is encountered, a null pointer is returned and errno is not changed. The POSIX readdir_r() returns 0 if successful or an error number to indicate failure. ---------8<------------------------------------------------------ Please check this out and if nobody objects, I will commit this next week. --Jani Index: reentrancy.c =================================================================== RCS file: /repository/php4/main/reentrancy.c,v retrieving revision 1.23 diff -u -r1.23 reentrancy.c --- reentrancy.c 2000/06/12 14:11:39 1.23 +++ reentrancy.c 2000/11/26 02:22:20 @@ -104,15 +104,15 @@ errno = 0; ret = readdir_r(dirp, entry); - - if (ret == 0) - *result = entry; - else if (errno == 0) { + + if (!ret || errno != 0) { *result = NULL; - ret = 0; + } else { + *result = entry; } + + return errno; - return ret; #else struct dirent *ptr; int ret = 0;
