Synopsis¶

#include <unistd.h>

int seteuid(uid_t uid);

Status¶

Declared, not implemented

Conformance¶

IEEE Std 1003.1-2017

Description¶

If uid is equal to the real user ID or the saved set-user-ID, or if the process has appropriate privileges, seteuid() shall set the effective user ID of the calling process to uid; the real user ID and saved set-user-ID shall remain unchanged.

The seteuid() function shall not affect the supplementary group list in any way.

Return value¶

Upon successful completion, 0 shall be returned; otherwise, -1 shall be returned and errno set to indicate the error.

Errors¶

The seteuid() function shall fail if:

EINVAL - The value of the uid argument is invalid and is not supported by the implementation.
EPERM - The process does not have appropriate privileges and uid does not match the real user ID or the saved set-user-ID.
