acl_copy_ext
acl_copy_ext(3) Library Functions Manual acl_copy_ext(3) NAME
acl_copy_ext - Copies the ACL from internal working space format to a contiguous, persistent form of the ACL LIBRARY
Security Library (libpacl.a) SYNOPSIS
#include <sys/acl.h> int acl_copy_ext( void *buf_p, acl_t acl_d, ssize_t size); PARAMETERS
User space to copy the contiguous, persistent for of the ACL into. Specifies the working storage, internal format ACL to copy. Indicates the size of the buffer pointed to by buf_p. DESCRIPTION
NOTE: This function is based on Draft 13 of the POSIX P1003.6 standard. The acl_copy_ext() function copies the contents of the ACL in internal working space format, pointed to by acl_d, into the buffer pointed to by buf_p. The ACL copied into the buffer is in contiguous, persistent formatxi and is not NULL terminated. RETURN VALUES
Upon successful completion, the acl_copy_ext function returns the size of the ACL copied. Otherwise, a value of -1 is returned and errno is set to indicate the error. ERRORS
If any of the following conditions occur, the acl_copy_ext() function sets errno to the corresponding value: The size parameter is zero or negative. The ACL referenced by acl_d contains one or more improperly formed ACL entries, or for some other reason can not be translated into con- tiguous format. The size parameter is greater than 0, but smaller than the ACL to be copied. RELATED INFORMATION
