sys_fsetxattr [fs/xattr.c]
Sets an extended attribute value. Extended attributes are name:value pairs associated with inodes (files, directories, symlinks, etc). They are extensions to the normal attributes which are associated with all inodes in the system (i.e. the sys_stat data). This system call is identical to sys_setxattr except that an open file descriptor (as returned by sys_open) is interrogated in place of path. Arguments
eax | 228
ebx | An open file descriptor.
ecx | Pointer to a null-terminated string that specifies the name. The name attribute includes a namespace prefix; there may be several, disjoint namespaces associated with an individual inode.
edx | Pointer to a null-terminated string that specifies the value.
esi | Size of the string pointed by edx.
edi | Flags. This parameter can be used to refine the semantics of the operation. XATTR_CREATE specifies a pure create, which fails if the named attribute exists already. XATTR_REPLACE specifies a pure replace operation, which fails if the named attribute does not already exist. By default (no flags), the extended attribute will be created if need be, or will simply replace the value if the attribute exists.
Return values If the system call succeeds the return value is 0. If the system call fails the return value is one of the following errno values:
`-ENOATTR` | `The named attribute does not exist, or the process has no access to this attribute.`
`-ENOTSUP` | `Extended attributes are not supported by the filesystem, or are disabled.`
`-EBADF` | `File descriptor specified by ebx is invalid.`
`-ENOMEM` | `Out of memory (i.e. kernel memory).`
`-EEXIST` | `XATTR_CREATE was specified, and the attribute existed already.`
`-ENOATTR.` | `XATTR_REPLACE was specified, and the attribute didn't exist.`
`-ENOSPC` | `Insufficient space to store the extended attribute.`
`-EDQUOT` | `Quota enforcement took place.`
