);

char *error_diagnosis,
size_t error_diag_len
);
DESCRIPTION
The drmaa_strerror() function returns a message text associated with
the DRMAA error number, drmaa_errno. For invalid DRMAA error codes
`NULL' is returned.
drmaa_get_contact()
The drmaa_get_contact() returns an opaque string containing contact
information related to the current DRMAA session to be used with the
drmaa_init(3) function. The opaque string contains the information
required by drmaa_init() to reconnect to the current session instead of
creating a new session. drmaa_init(3) function.
The drmaa_get_contact() function returns the same value before and
after drmaa_init(3) is called.
drmaa_version()
The drmaa_version() function returns into the integers pointed to by
major and minor, the major and minor version numbers of the DRMAA
library. For a DRMAA 1.0 compliant implementation `1' and `0' will be
returned in major and minor, respectively.
drmaa_get_DRM_system()
The drmaa_get_DRM_system() function returns into drm_system up to
drm_system_len characters of a string containing Sun Grid Engine
product and version information.
The drmaa_get_DRM_system() function returns the same value before and
after drmaa_init(3) is called.
drmaa_get_DRMAA_implementation()
The drmaa_get_DRMAA_implementation() function returns into drm_system
up to drm_system_len characters of a string containing the Sun Grid
Engine DRMAA implementation version information. In the current
implementation, the drmaa_get_DRMAA_implementation() function returns
the same result as the drmaa_get_DRM_system() function.
The drmaa_get_DRMAA_implementation() function returns the same value
before and after drmaa_init(3) is called.
ENVIRONMENTAL VARIABLES
SGE_ROOT Specifies the location of the Sun Grid Engine standard
configuration files.
SGE_CELL If set, specifies the default Sun Grid Engine cell to be
used. To address a Sun Grid Engine cell Sun Grid Engine
uses (in the order of precedence):
The name of the cell specified in the environment
variable SGE_CELL, if it is set.
The name of the default cell, i.e. default.
SGE_DEBUG_LEVEL
If set, specifies that debug information should be
written to stderr. In addition the level of detail in
which debug information is generated is defined.
SGE_QMASTER_PORT
If set, specifies the tcp port on which sge_qmaster(8)
is expected to listen for communication requests. Most
installations will use a services map entry instead to
define that port.
RETURN VALUES
Upon successful completion, drmaa_get_contact(), drmaa_version(), and
drmaa_get_DRM_system() return DRMAA_ERRNO_SUCCESS. Other values
indicate an error. Up to error_diag_len characters of error related
diagnosis information is then provided in the buffer error_diagnosis.
ERRORS
The drmaa_get_contact(), drmaa_version(), drmaa_get_DRM_system(), and
drmaa_get_DRMAA_implementation() will fail if:
DRMAA_ERRNO_INTERNAL_ERROR
Unexpected or internal DRMAA error, like system call failure, etc.
DRMAA_ERRNO_DRM_COMMUNICATION_FAILURE
Could not contact DRM system for this request.
DRMAA_ERRNO_AUTH_FAILURE
The specified request is not processed successfully due to
authorization failure.
DRMAA_ERRNO_INVALID_ARGUMENT
The input value for an argument is invalid.
DRMAA_ERRNO_NO_MEMORY
Failed allocating memory.
The drmaa_get_contact() and drmaa_get_DRM_system() will fail if:
DRMAA_ERRNO_NO_ACTIVE_SESSION
Failed because there is no active session.
