GC_PARM_BLK

---

typedef struct {
    unsigned short    parm_data_size;
    unsigned char     parm_data_buf[1]; 
}GC_PARM_BLK, *GC_PARM_BLKP; 

Description

The GC_PARM_BLK structure contains parameter data. To retrieve or update parameter data, the parameter data must be in the format of the GC_PARM_DATA data structure. See Table  21, "Possible Set ID, Parm ID Pairs used in GCLIB_MAKECALL_BLK Structure" or the appropriate Global Call Technology User's Guide to find the set IDs and parameter IDs to be used in the GC_PARM_DATA structure. See Figure 2, "GC_PARM_BLK Memory Diagram" for an illustration of the memory block format.

Note: Memory allocation and deallocation of a GC_PARM_BLK data block is done by the Global Call utility functions (gc_util_xxx). See Section 1.12, "GC_PARM_BLK Utility Functions" for more information.

Field Descriptions

The fields of GC_PARM_BLK are described as follows:

parm_data_size

the size of the parm_data_buf buffer in bytes

parm_data_buf[1]

the first byte of the first element in an array of GC_PARM_DATA structures. The memory for this buffer is allocated dynamically by the utility functions.
