evalformake Handler

RTEMS Filesystem Design Guide

5.4.1.2: evalformake Handler

Corresponding Structure Element:

evalformake

Arguments:

   const char                       *path,       /* IN */
   rtems_filesystem_location_info_t *pathloc,    /* IN/OUT */
   const char                      **name        /* OUT    */

Description:

This method is given a path to evaluate and a valid start location. It is responsible for finding the parent node for a requested make command, setting pathloc information to identify the parent node, and setting the name pointer to the first character of the name of the new node. Additionally, if the filesystem supports the mount command, this method should call the evalformake routine for the mounted filesystem.

This routine returns a 0 if the evaluation was successful. Otherwise, it returns a -1 and sets errno to the correct error.

This routine is required and should NOT be set to NULL. However, if the filesystem does not support user creation of a new node, it may set errno to ENOSYS and return -1.
