euidaccess, eaccess − check effective user’s permissions for a file
#define
_GNU_SOURCE /* See feature_test_macros(7) */
#include <unistd.h>
int
euidaccess(const char *pathname, int
mode);
int eaccess(const char *pathname, int
mode);
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.
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.
As for access(2).
The eaccess() function was added to glibc in version 2.4.
These functions are nonstandard. Some other systems have an eaccess() function.
access(2), chmod(2), chown(2), faccessat(2), open(2), setgid(2), setuid(2), stat(2), credentials(7), path_resolution(7)
