.SH "NAME"
getfilecon, fgetfilecon, lgetfilecon \- get SELinux security context of a file
.SH "SYNOPSIS"
.B #include <selinux/selinux.h>
.sp
.BI "int getfilecon(const char *" path ", security_context_t *" con );
.BI "int lgetfilecon(const char *" path ", security_context_t *" con );
.BI "int fgetfilecon(int "fd ", security_context_t *" con );
.SH "DESCRIPTION"
.B getfilecon
retrieves the context associated with the given path in the file system, the
length of the context is returned.
.B lgetfilecon
is identical to getfilecon, except in the case of a symbolic link, where the
link itself is interrogated, not the file that it refers to.
.B fgetfilecon
is identical to getfilecon, only the open file pointed to by filedes (as
returned by open(2)) is interrogated in place of path.
The returned context should be freed with freecon if non-NULL.
.SH "RETURN VALUE"
On success, a positive number is returned indicating the size of the
extended attribute value. On failure, \-1 is returned and errno is set
appropriately.
If the context does not exist, or the process has no access to
this attribute, errno is set to ENODATA.
If extended attributes are not supported by the filesystem, or are dis\-
abled, errno is set to ENOTSUP.
The errors documented for the stat(2) system call are also applicable
here.
