In pSOS+ TCP/IP module pNA+, where are disallocated message blocks?
hello, I have a problem in pNA+. I have poor English. sorry ^^;
when there is receive data, Network Interface allocates message block in order to send received data to pNA+.(I used pna_esballoc() for zero copy.) I think that the message blocks must be disallocated. but where? The free operation is worked by pNA+, automatically? If it is not, developer must write the free system call?
If I write "NC_BUFS_0 256" in sys_conf.h My program stop at 257th-pna_esballoc().
If I write "NC_BUFS_0 32" in sys_conf.h My program stop at 33th-pna_esballoc().
What is problem?
Thank you for reading of my quastion.
