Function Details

static uint8_t* ocs_find_vpd ( uint8_t *  vpddata, uint32_t  vpddata_length, const char *  key  )

inlinestatic

find a VPD entry

Finds a VPD entry given the two character code

Parameters

vpddata	pointer to raw vpd data buffer
vpddata_length	length of vpddata buffer in bytes
key	key to look up

Returns

returns a pointer to the key location or NULL if not found or checksum error

Definition at line 123 of file ocs_vpd.h.

static int vpddone ( vpdbuf_t *  vpd )

inlinestatic

return true if no more vpd buffer data

return true if the vpd buffer data has been completely consumed

Parameters

vpd	pointer to vpd buffer

Returns

returns true if no more data

Definition at line 85 of file ocs_vpd.h.

static int vpdnext ( vpdbuf_t *  vpd )

inlinestatic

return next VPD byte

Returns next VPD byte and updates accumulated checksum

Parameters

vpd	pointer to vpd buffer

Returns

returns next byte for success, or a negative error code value for failure.

Definition at line 64 of file ocs_vpd.h.

static uint8_t* vpdref ( vpdbuf_t *  vpd )

inlinestatic

return pointer to current VPD data location

Returns a pointer to the current location in the VPD data

Parameters

vpd	pointer to vpd buffer

Returns

pointer to current VPD data location
