Manual Section... (3) - page: euidaccess
NAMEeuidaccess, eaccess - check effective user's permissions for a file
#define _GNU_SOURCE #include <unistd.h> int euidaccess(const char *pathname, int mode); int eaccess(const char *pathname, int mode);
DESCRIPTIONLike 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).
RETURN VALUEOn 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.
ERRORSAs for access(2).
VERSIONSThe eaccess() function was added to glibc in version 2.4.
CONFORMING TOThese functions are nonstandard. Some other systems have an eaccess() function.
