+Synopsis
+========
+
+`#include <ts/ts.h>`
+
+.. function:: TSReturnCode TSMgmtSourceGet(const char * var_name,
TSMgmtSource * result)
+
+Description
+===========
+
+Get the source of a value for a configuration variable. :arg:`var_name` is
the name of the variable
+as a nul terminated string. The source value is stored in :arg:`result`.
The function can return
+failure if :arg:`var_name` is not found.
+
+Types
+=====
+
+.. type:: TSMgmtSource
+
+ Source of the current value for a management (configuration) value.
+
+ .. macro:: TS_MGMT_SOURCE_NULL
+
+ Invalid value, no source available. This is primarily used as an
initialization or error value
+ and should be returned only when an API call fails.
+
+ .. macro:: TS_MGMT_SOURCE_DEFAULT
+
+ The default value provided by the |TS| core.
+
+ .. macro:: TS_MGMT_SOURCE_PLUGIN
+
+ The default value provided by a plugin. This means the configuration
variable itself was
+ created by a plugin and is not part of the |TS| core and the value
has not been changed from
+ that default.
+
+ .. macro:: TS_MGMT_SOURCE_EXPLICIT
+
+ The value has been set in :file:`records.config` or via an explict
API call (such as
+ :c:func:`TSMgmtIntSet`). Note this does not guarantee the value is
not the default value, as
+ the variable could have been set to that value. This only means an
administrator or plugin
+ explicit set the value.
+
+ .. macro:: TS_MGMT_SOURCE_ENV
+
+ The value was retrived from the process environment, overriding the
default value.
