LIBRARY
Linux Access Control Lists library (libacl, -lacl).
SYNOPSIS
#include <sys/types.h> #include <sys/acl.h> int acl_get_tag_type(acl_entry_t entry_d, acl_tag_t *tag_type_p);
DESCRIPTION
The acl_get_tag_type() function assigns to the value pointed to by tag_type_p the tag type for the ACL entry indicated by the argument entry_d. The argument entry_d and any other ACL entry descriptors that refer to entries in the same ACL continue to refer to those entries. The order of all existing entries in the ACL remain unchanged.
RETURN VALUE
The acl_get_tag_type() function returns the value 0 if successful; otherwise the value -1 is returned and the global variable errno is set to indicate the error.
ERRORS
If any of the following conditions occur, the acl_get_tag_type() function returns -1 and sets errno to the cor- responding value: [EINVAL] The argument entry_d is not a valid descriptor for an ACL entry.
STANDARDS
IEEE Std 1003.1e draft 17 ("POSIX.1e", abandoned)
