aa_splitcon - split the confinement context into a label and mode

#include <sys/apparmor.h>

char *aa_splitcon(char *con, char **mode);

Link with -lapparmor when compiling.

The aa_splitcon() function splits a confinement context into separate label and mode strings. The @con string is modified so that the label portion is NUL terminated. The enforcement mode is also NUL terminated and the parenthesis surrounding the mode are removed. If @mode is non-NULL, it will point to the first character in the enforcement mode string on success.

The Linux kernel’s /proc/<PID>/attr/current interface appends a trailing newline character to AppArmor contexts that are read from that file. If @con contains a single trailing newline character, it will be stripped by aa_splitcon() prior to all other processing.

Returns a pointer to the first character in the label string. NULL is returned on error.
