Gets the configuration values of a topology.
int
tpm_infobuildvar(
ade_id tpm_id,
ade_id var_id);
Returns RTNORM or an error code.
| tpm_id | Topology ID. |
| var_id | Topology variables ID. |
The topology variables ID references a set of topology variables in which to store the values that this function gets.
If no topology variables are allocated, call tpm_varalloc to allocate a set of them and return their ID.
To read the values that this function gets, use tpm_varget or tpm_varlist. To build a new topology using these variables, use tpm_mntbuild.
The following sample opens a topology, reads its configuration values using tpm_infobuildvar(), and gets its node layer. The topology is then closed, unloaded and the resbuf is released as required.
char* pszTopoName = "I-95_Corridor";
int resultCode = tpm_acload(pszTopoName, 0);
ade_id topoId = tpm_acopen(pszTopoName, 0);
ade_id topoConfigVarId = tpm_varalloc();
resultCode = tpm_infobuildvar(
topoId,
topoConfigVarId);
char* pszConfigVarName = "NODE_LAYER";
struct resbuf* pConfigVarsRb = acutBuildList(RTSTR, "", 0);
resultCode = tpm_varget(
topoConfigVarId,
pszConfigVarName,
pConfigVarsRb);
if (RTNORM == resultCode){
acutPrintf(
"\nThe %s variable in the %s topology contains the value \"%s\"."
, pszConfigVarName, pszTopoName, pConfigVarsRb->resval.rstring);
}
else {
acutPrintf(
"\nCould not determine the %s variable value."
, pszConfigVarName);
}
resultCode = tpm_acclose(topoId);
resultCode = tpm_acunload(pszTopoName);
acutRelRb(pConfigVarsRb);
