EUIDACCESS(3)						     Linux Programmer's Manual						     EUIDACCESS(3)

NAME

       euidaccess, eaccess - check effective user's permissions for a file

SYNOPSIS

       #define _GNU_SOURCE
       #include <unistd.h>

       int euidaccess(const char *pathname, int mode);
       int eaccess(const char *pathname, int mode);

DESCRIPTION

       Like access(2), euidaccess() checks permissions and existence of the file identified by its argument pathname.  However, whereas access(2),
       performs checks using the real user and group identifiers of the process, euidaccess() uses the effective identifiers.

       mode is a mask consisting of one or more of R_OK, W_OK, X_OK and F_OK, with the same meanings as for access(2).

       eaccess() is a synonym for euidaccess(), provided for compatibility with some other systems.

RETURN VALUE

       On success (all requested permissions granted), zero is returned.  On error (at least one bit in  mode  asked  for  a  permission  that	is
       denied, or some other error occurred), -1 is returned, and errno is set appropriately.

ERRORS

       As for access(2).

VERSIONS

       The eaccess() function was added to glibc in version 2.4.

CONFORMING TO

       These functions are nonstandard.  Some other systems have an eaccess() function.
