Function Documentation

const char* gras_os_myname

(

void

)

get the fully-qualified name of the current host

Returns the fully-qualified name of the host machine, or "localhost" if the name cannot be determined. Always returns the same value, so multiple calls cause no problems.

const char* gras_os_hostport

(

void

)

get the uri of the current process

Returns the concatenation of gras_os_myname():gras_os_myport(). Please do not free the result.

int gras_os_getpid

(

void

)

get process identification

Returns the process ID of the current process. (This is often used by routines that generate unique temporary file names.)

xbt_dict_t gras_process_properties

(

void

)

retrieve the process properties dictionnary

Warning

it's the original one, not a copy. Don't mess with it

xbt_dict_t gras_os_host_properties

(

void

)

retrieve the host properties dictionary

Warning

it's the original one, not a copy. Don't mess with it
