drmaa_get_DRM_system(3) Miscellaneous DRMAA functions.

Other Alias

drmaa_strerror, drmaa_get_contact, drmaa_version

SYNOPSIS

#include drmaa.h

const char *drmaa_strerror(

int 
drmaa_errno

); 

int drmaa_get_contact(
char *contact, size_t contact_len, char *error_diagnosis, size_t error_diag_len
); 

int drmaa_version(
unsigned int *major, unsigned int *minor, char *error_diagnosis, size_t error_diag_len
); 

int drmaa_get_DRM_system(
char *drm_system, size_t drm_system_len, char *error_diagnosis, size_t error_diag_len
); 

int drmaa_get_DRMAA_implementation(
char *drm_impl, size_t drm_impl_len, 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
function. The opaque string contains the information required by drmaa_init()
to reconnect to the current session instead of creating a new session.
function.


The drmaa_get_contact() function returns the same value before and after
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 Grid Engine product and 
version information.


The drmaa_get_DRM_system() function returns the same value before and after
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 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
is called.












ENVIRONMENTAL VARIABLES






SGE_ROOT

Specifies the location of the Grid Engine standard configuration files.

SGE_CELL

If set, specifies the default Grid Engine cell to be used. To address a Grid Engine
cell 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
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() can fail with:



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() can fail with:



DRMAA_ERRNO_NO_ACTIVE_SESSION



Failed because there is no active session.
