acl_get_entry - Returns a descriptor to an ACL entry
Security Library (libpacl.a)
Specifies the working storage internal representation ACL descriptor.
NOTE: This function is based on Draft 13 of the POSIX P1003.6 standard. The function may change as the P1003.6 standard is finalized.
The acl_get_entry() function returns a pointer to the next entry in the specified ACL.
Following a call to the acl_get_fd(),acl_get_file(), acl_from_text(), or acl_first_entry() function, the first call to the acl_get_entry() function obtains the first entry in the ACL. Subsequent calls obtain successive entries in the ACL, until the last entry is obtained. After the last entry has been obtained, the value 0 (zero) is returned.
If any of the following conditions occur, the acl_get_entry() function sets errno to the corresponding value:
Upon successful completion, the acl_get_entry() function returns a pointer to the ACL entry descriptor. If the last ACL has already been returned by a previous call to this function, or the ACL has no ACL entries, the function returns a value of 0 (zero). Otherwise, a value of -1 is returned, and errno is set to indicate the error.
The acl_d parameter does not refer to a valid ACL entry. The position of the ACL entry must be reset using the acl_first_entry library routine.
