+/* This function is called by receive_check_fs() below, and also by string
+expansion for variables such as $spool_space. The field names for the statvfs
structure are macros, because not all OS have F_FAVAIL and it seems tidier to
have macros for F_BAVAIL and F_FILES as well. Some kinds of file system do not
have inodes, and they return -1 for the number available.
Later: It turns out that some file systems that do not have the concept of
inodes return 0 rather than -1. Such systems should also return 0 for the total
-number of inodes, so we require that to be greater than zero before returning
+number of inodes, so we require that to be greater than zero before returning
an inode count.
Arguments:
isspool TRUE for spool partition, FALSE for log partition
inodeptr address of int to receive inode count; -1 if there isn't one
-
+
Returns: available on-root space, in kilobytes
- -1 for log partition if there isn't one
-
-All values are -1 if the STATFS functions are not available.
+ -1 for log partition if there isn't one
+
+All values are -1 if the STATFS functions are not available.
