EUIDACCESS(3) Linux Programmers Manual EUIDACCESS(3)
NAME
euidaccess, eaccess - check effective users permissions for a file
SYNOPSIS
#define _GNU_SOURCE
#include
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 pro
cess, 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 appro
priately.
ERRORS
As for access(2).
VERSIONS
The eaccess() function was added to glibc in version 2.4.
CONFORMING TO
These functions are non-standard. Some other systems have an eaccess()
function.
SEE ALSO
access(2), chmod(2), chown(2), faccessat(2), open(2), setgid(2),
setuid(2), stat(2), credentials(7), path_resolution(7)
