NAME

       drmaa_strerror,  drmaa_get_contact,  drmaa_version,  drmaa_get_DRM_system  - Miscellaneous
       DRMAA functions.

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 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 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  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 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 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() 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.
