Hi All,
I'm porting a autodefinition exit to zOS for populating attributes of CLUSSDR after fetching the values from a member present in PDSE. Recfm for PDSE is FB. Now, from all the research I know that I have to use fread() to read from a record base PDSE. But, fread statement doesn't return anything in the buffer. Can someone help in letting me know if I'm doing something wrong?
Code :
if ((cfgFile=fopen(temp,"r,recfm=FB") == NULL )) {
return CFG_NO_FILE;
}
loopcount=0;
while ( !feof(cfgFile) && loopcount < 15) {
memset(line,0x00,80);
loopcount++;
count = fread( line, 1, 80, cfgFile);
trimStr(line);
TRACE TPRINTF(("%s \nCOUNT =%d NAME=%s\n ",count,line));
/* Ignore if blank line or comment */
if (line[0] == '\0' || line[0] == '#') {
continue;
}
....
....
....
}
Any help is greatly appreciated.
Thanks & Regards |

Any relevant errors or informational messages in the SYSLOG for the CHIN or qmgr?

Yes, temp has the value for the DSN having the config member and it is successfully getting accessed. (If I remove the member channels end with config file missing statement).
there no relevant messages in CHIN or MSTR as the channel starts after trying to fecht data from config member 15 times(loopcount) if I don't use loopcount it goes in an infinite loop.
Thanks & Regards |

blockip2 is a channel exit written in c running on z/os too. it is also able to read a configuration file. maybe you can have a look at its source code how it is done there.
