NAME

       sepol_genbools - Rewrite a binary policy with different boolean settings

SYNOPSIS

       #include <sepol/sepol.h>

       int sepol_genbools(void *data, size_t len, const char *boolpath);
       int sepol_genbools_array(void *data, size_t len, char **names, int *values, int nel);

DESCRIPTION

       sepol_genbools  rewrites  a binary policy stored in the memory region described by (data, len) to use the
       boolean settings specified in the file  named  by  boolpath.   The  boolean  settings  are  specified  by
       name=value  lines  where value may be 0 or false to disable or 1 or true to enable.  The binary policy is
       rewritten in place in memory.

       sepol_genbools_array does likewise, but obtains the boolean settings from  the  parallel  arrays  (names,
       values) with nel elements each.

RETURN VALUE

       Returns  0  on  success or -1 otherwise, with errno set appropriately.  An errno of ENOENT indicates that
       the boolean file did not exist.  An errno of EINVAL indicates that one or more  booleans  listed  in  the
       boolean  file  was  undefined  in  the policy or had an invalid value specified; in this case, the binary
       policy is still rewritten but any invalid boolean settings are ignored.
