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.
