d_lookup — search for a dentry


struct dentry * d_lookup (const struct dentry * parent,
 const struct qstr * name);


const struct dentry * parent

parent dentry

const struct qstr * name

qstr of name we wish to find


dentry, or NULL

d_lookup searches the children of the parent dentry for the name in question. If the dentry is found its reference count is incremented and the dentry is returned. The caller must use dput to free the entry when it has finished using it. NULL is returned if the dentry does not exist.
