pSOS+ System Calls pt_create PT_GLOBAL / PT_LOCAL Partition is globally addressable by other nodes / partition can be addressed only the by local node. The single-processor version of the pSOS+ kernel ignores PT_GLOBAL. PT_DEL / PT_NODEL Deletion of the partition with pt_delete() is enabled, even if one or more buffers are allocated. Deletion of the partition is prohibited unless all buffers have been freed. ptid Points to the variable where pt_create() stores the partition ID of the named partition. nbuf Points to the variable where pt_create() stores the number of actual buffers in the partition. Return Value This call returns 0 on success or an error code on failure. Error Codes Hex Mnemonic Description 0x08 ERR_OBJTFULL Node's object table full. 0x28 ERR_PTADDR Starting address not on long word boundary. 0x29 ERR_BUFSIZE Buffer size not power of 2, or less than 4 bytes. 0x2A ERR_TINYPT Length too small to hold the partition control information. Notes 1. Internally, the pSOS+ kernel treats a partition name as a 32-bit integer. However, when the application calls the kernel through the pSOS+ C language API, it passes the partition name as a four-byte character array. 2. The pSOS+ kernel does not check for duplicate partition names. If duplicate names exist, a pt_ident() call can return the ptid of any partition with the duplicate name. pSOSystem System Calls 1-49 1
