MIO_DEBUG
The purpose of the MIO_DEBUG environment variable is to aid in debugging MIO.
MIO searches MIO_DEFAULTS for keywords and provides
debugging output for the option. The available keywords are:
- ALL
- Turns on all the MIO_DEBUG environment variable keywords.
- ENV
- Outputs environment variable matching requests.
- OPEN
- Outputs open requests made to the MIO_open64 subroutine.
- MODULES
- Outputs modules invoked for each call to the MIO_open64 subroutine.
- TIMESTAMP
- Places into a stats file a timestamp preceding each entry.
- DEF
- Outputs the definition table of each module. This dump is executed for all MIO library modules when the file opens.
