PVK_insert( ) |
Write a New Record |
int PVK_insert(int fh, char *dtabfr, int dtasz, char *keybfr, int keysz);
Where:
|
fh |
File handle returned from a prior call to PVK_OpenExt( ) |
|
dtabfr |
Pointer to the data buffer to receive the record data |
|
dtasz |
Size of the record in bytes |
|
keybfr |
Pointer to a buffer containing the external key, if applicable |
|
keysz |
Size of the external key in bytes |
PVK_insert( ) is used to write a new record into a PxPlus keyed, indexed or EFF file. It returns an error if a record with the same key value exists.
The data buffer must contain a properly formatted record with the length of the record specified. The value supplied in dtasz should contain the actual size of the record rather than the size of the data buffer. PVK_insert( ) will pad the data record with nulls as required for files with fixed length records.
The key buffer and length must contain the necessary key information for a file with an external key. If no external key is defined for the file, then the keysz field must be set to zero.
The calling application is responsible for constructing a valid PxPlus data record using field separators as required.
If successful, this function will return 0; otherwise, it will return -1.
