.SH "NAME"
sepol_genbools \- Rewrite a binary policy with different boolean settings
.SH "SYNOPSIS"
.B #include <sepol/sepol.h>
.sp
.BI "int sepol_genbools(void *" data ", size_t "len ", char *" boolpath );

.BI "int sepol_genbools_array(void *" data ", size_t " len ", char **" names ", int *" values ", int " nel );

.SH "DESCRIPTION"
.B 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.

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

.SH "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.
