# PX\_get\_data\_bytes(3)

Get value from bytes data field

## NAME

PX\_get\_data\_bytes — Get value from bytes data field

## SYNOPSIS

\#include \<paradox.h\>

int PX\_get\_data\_bytes(pxdoc\_t \*pxdoc, char \*data, int len, char \*\*value)

## DESCRIPTION

Reads a data field consisting of an array of bytes into  a chunk of memory and returns the pointer to it in  **value**. The memory is allocated by this function  and must be freed by the calling application. You should use this function  instead of accessing the data directly.

**data** points to the start of the data field in the  record. It must be calculated by summing up all field length before  the field to operate on and add it to the base pointer of the  record.

**Note:**

**This function is deprecated and obsolete if**  **[PX\_retrieve\_record(3)](/PX_retrieve_record/3.md) is used.**

## RETURN VALUE

**Returns 0 if the value is NULL, -1 in case of an error and 1**  **otherwise.**
