    NAME

    futimes, lutimes - change file timestamps
     
    

    SYNOPSIS

    #include <sys/time.h>
    
    int futimes(int fd, const struct timeval tv[2]);
    
    int lutimes(const char *filename, const struct timeval tv[2]);
    

    Feature Test Macro Requirements for glibc (see feature_test_macros(7)):

    futimes(), lutimes(): _BSD_SOURCE  

    DESCRIPTION

    futimes() changes the access and modification times of a file in the same way as utimes(2), with the difference that the file whose timestamps are to be changed is specified via a file descriptor, fd, rather than via a pathname.

    lutimes() changes the access and modification times of a file in the same way as utimes(2), with the difference that if filename refers to a symbolic link, then the link is not dereferenced: instead, the timestamps of the symbolic link are changed.  

    RETURN VALUE

    On success, zero is returned. On error, -1 is returned, and errno is set appropriately.  

    ERRORS

    Errors are as for utimes(2), with the following additions for futimes():
    EBADF
    fd is not a valid file descriptor.
    ENOSYS
    The /proc file system could not be accessed.
     

    VERSIONS

    futimes() is available since glibc 2.3. lutimes() is available since glibc 2.6, and is implemented using the utimensat(2) system call, which is supported since kernel 2.6.22.  

    CONFORMING TO

    These functions are not specified in any standard. Other than Linux, they are only available on the BSDs.
