pvm_mytid(1) Scilab function pvm_mytid(1)
NAME
pvm_mytid - returns the tid of the calling process.
CALLING SEQUENCE
[tid] = pvm_mytid()
PARAMETERS
tid : integer, the task identifier of the calling PVM process. Values
less than zero indicate an error.
DESCRIPTION
pvm_mytid enrolls this process into PVM on its first call. It also gen-
erates a unique tid if this process was not created by pvm_spawn.
pvm_mytid returns the tid of the calling process and can be called multiple
times in an application.
Any PVM system call (not just pvm_mytid) will enroll a task in PVM if the
task is not enrolled before the call.
The tid is a 32 bit positive integer created by the local pvmd. The 32
bits are divided into fields that encode various information about this
process such as its location in the virtual machine (i.e. local pvmd
address), the CPU number in the case where the process is on a multiproces-
sor, and a process ID field. This information is used by PVM and is not
expected to be used by applications. Applications should not attempt to
predict or interpret the tid with the exception of calling tidtohost()
If PVM has not been started before an application calls pvm_mytid the
returned tid will be < 0.
EXAMPLE
tid = pvm_mytid()
SEE ALSO
pvm_tidtohost, pvm_parent
