## Function Documentation

OPAL_DECLSPEC int opal_util_keyval_parse | ( | const char * | filename,
|  | opal_keyval_parse_fn_t | callback
| ) |  |

Parse `filename`, made up of key = value pairs.

Parse `filename`, made up of key = value pairs. For each line that appears to contain a key = value pair, `callback` will be called exactly once. In a multithreaded context, calls to opal_util_keyval_parse() will serialize multiple calls.

## Variable Documentation

BEGIN_C_DECLS typedef void(* opal_keyval_parse_fn_t)(const char *key, const char *value)

Callback triggered for each key = value pair.

Callback triggered from opal_util_keyval_parse for each key = value pair. Both key and value will be pointers into static buffers. The buffers must not be free()ed and contents may be overwritten immediately after the callback returns.
