NAME
slurm_free_ctl_conf, slurm_load_ctl_conf, slurm_print_ctl_conf - Slurm
information reporting functions
SYNTAX
#include <stdio.h>
#include <slurm/slurm.h>
long slurm_api_version ();
void slurm_free_ctl_conf (
slurm_ctl_conf_t *conf_info_msg_ptr
);
int slurm_load_ctl_conf (
time_t update_time,
slurm_ctl_conf_t **conf_info_msg_pptr
);
void slurm_print_ctl_conf (
FILE *out_file,
slurm_ctl_conf_t *conf_info_msg_ptr
);
ARGUMENTS
conf_info_msg_pptr
Specifies the double pointer to the structure to be created and
filled with the time of the last configuration update and
detailed configuration information. Configuration information
includes control machine names, file names, timer values, etc.
See slurm.h for full details on the data structure’s contents.
conf_info_msg_ptr
Specifies the pointer to the structure created by
slurm_load_ctl_conf.
out_file
Specifies the file to print data to.
update_time
For all of the following informational calls, if update_time is
equal to or greater than the last time changes where made to
that information, new information is not returned. Otherwise
all the configuration. job, node, or partition records are
returned.
DESCRIPTION
slurm_api_version Return the SLURM API version number.
slurm_free_ctl_conf Release the storage generated by the
slurm_load_ctl_conf function.
slurm_load_ctl_conf Returns a slurm_ctl_conf_t that contains Slurm
configuration records.
slurm_print_ctl_conf Prints the contents of the data structure loaded
by the slurm_load_ctl_conf function.
RETURN VALUE
For slurm_api_version the SLURM API version number is returned. All
other functions return zero on success and -1 on error with the SLURM
error code set appropriately.
ERRORS
SLURM_NO_CHANGE_IN_DATA Data has not changed since update_time.
SLURM_PROTOCOL_VERSION_ERROR Protocol version has changed, re-link your
code.
SLURM_PROTOCOL_SOCKET_IMPL_TIMEOUT Timeout in communicating with SLURM
controller.
EXAMPLE
#include <stdio.h>
#include <slurm/slurm.h>
#include <slurm/slurm_errno.h>
int main (int argc, char *argv[])
{
slurm_ctl_conf_t * conf_info_msg_ptr = NULL;
long version = slurm_api_version;
/* We can use the SLURM version number to determine how
* API should be used */
printf("slurm_api_version: %ld, %ld.%ld.%ld\n", version,
SLURM_VERSION_MAJOR(version),
SLURM_VERSION_MINOR(version),
SLURM_VERSION_MICRO(version));
/* get and print some configuration information */
if ( slurm_load_ctl_conf ((time_t) NULL,
&conf_info_msg_ptr ) ) {
slurm_perror ("slurm_load_ctl_conf error");
exit (1);
}
/* The easy way to print */
slurm_print_ctl_conf (stdout,
conf_info_msg_ptr);
/* The hard way */
printf ("control_machine = %s\n",
slurm_ctl_conf_ptr->control_machine);
printf ("server_timeout = %u\n",
slurm_ctl_conf_ptr->server_timeout);
slurm_free_ctl_conf (conf_info_msg_ptr);
exit (0);
}
NOTE
These functions are included in the libslurm library, which must be
linked to your process for use (e.g. "cc -lslurm myprog.c").
