* NAME envGetLongConfigParam - get value of an integer config parameter
|
||||
*
|
||||
* DESCRIPTION
|
||||
* Gets the value of a configuration parameter and copies it
|
||||
* into the caller's integer (long) buffer. If the configuration
|
||||
* parameter isn't found in the environment, then the default value for
|
||||
* the parameter is copied.
|
||||
* If no parameter is found and there is no default, then ERROR is
|
||||
*
|
||||
* If no parameter is found and there is no default, then -1 is
|
||||
* returned and the callers buffer is unmodified.
|
||||
*
|
||||
* RETURNS
|
||||
* OK if the parameter is found and it is an integer or ERROR
|
||||
* 0, or
|
||||
* -1 if an error is encountered
|
||||
*
|
||||
* EXAMPLES
|
||||
* 1. Get the value for the integer environment parameter EPICS_NUMBER_OF_ITEMS.
