.TH semanage_query 3 "15 March 2006" "ivg2@cornell.edu" "Libsemanage API documentation"

|
|
.SH "NAME"
|
||
|
|
semanage_query \- SELinux Management API
|
||
|
|
|
||
|
|
.SH "SYNOPSIS"
|
||
|
|
The following query function is supported for any semanage record.
|
||
|
|
.br
|
||
|
|
Replace the function and object name as necessary.
|
||
|
|
|
||
|
|
.B extern int QUERY_FUNCTION (
|
||
|
|
.br
|
||
|
|
.BI " semanage_handle_t *" handle ","
|
||
|
|
.br
|
||
|
|
.BI " const semanage_OBJECT_key_t *" key ","
|
||
|
|
.br
|
||
|
|
.BI " semanage_OBJECT_t **" response ");"
|
||
|
|
|
||
|
|
.SH "DESCRIPTION"
|
||
|
|
.TP
|
||
|
|
.B Behavior:
|
||
|
|
The query function will fail if a matching key is not found. Otherwise, the corresponding object is returned.
|
||
|
|
|
||
|
|
.TP
|
||
|
|
.B Parameters:
|
||
|
|
The
|
||
|
|
.I handle
|
||
|
|
is used to track persistent state across semanage calls, and for error reporting. The
|
||
|
|
.I key
|
||
|
|
identifies the object being queried, which will be stored in the address pointed by
|
||
|
|
.I response
|
||
|
|
The key is a property of the caller, and will not be stored or modified internally. The object returned becomes a property of the caller, and must be freed with
|
||
|
|
.B semanage_OBJECT_free.
|
||
|
|
|
||
|
|
.TP
|
||
|
|
.B Requirements:
|
||
|
|
This function requires an semanage connection to be established (see
|
||
|
|
.BR semanage_connect "(3)"
|
||
|
|
)
|
||
|
|
|
||
|
|
.SH "RETURN VALUE"
|
||
|
|
In case of failure, \-1 is returned, and the semanage error callback is invoked, describing the error.
|
||
|
|
Otherwise a non-negative integer is returned (a commit number). The same number will be returned by all other semanage object read calls until the next commit.
