CentOS 7.0 - man page for fgetfilecon (centos section 3)

getfilecon(3)				      SELinux API documentation 				getfilecon(3)

getfilecon, fgetfilecon, lgetfilecon - get SELinux security context of a file
#include <selinux/selinux.h> int getfilecon(const char *path, security_context_t *con); int getfilecon_raw(const char *path, security_context_t *con); int lgetfilecon(const char *path, security_context_t *con); int lgetfilecon_raw(const char *path, security_context_t *con); int fgetfilecon(int fd, security_context_t *con); int fgetfilecon_raw(int fd, security_context_t *con);
getfilecon() retrieves the context associated with the given path in the file system, the length of the con- text is returned. 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. fgetfilecon() is identical to getfilecon(), only the open file pointed to by filedes (as returned by open(2)) is interrogated in place of path. getfilecon_raw(), lgetfilecon_raw() and fgetfilecon_raw() behave identically to their non-raw counterparts but do not perform context translation. The returned context should be freed with freecon(3) if non-NULL.
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 disabled, errno is set to ENOTSUP. The errors documented for the stat(2) system call are also applicable here.
