lrs_decimal_to_hex_string

Conversion Functions

Converts an integer into a HEX string.

char*  lrs_decimal_to_hex_string( char* s_desc, char* buf, long length );
s_desc A descriptor identifying an unbound socket.
buf A pointer to the buffer containing the decimal string.
length The length of the string.

The lrs_decimal_to_hex_string function converts an integer into a hexadecimal string. For example, if a string appears as 4, this function converts it to \x04.

The translated buffer is stored in the internal user buffer. To retrieve the contents of the buffer, use lrs_get_user_buffer. To determine the size of the buffer, use lrs_get_user_buffer_size.

Note that the following functions overwrite the same internal buffer (user buffer):

Parameterization

You cannot use standard parameterization for any arguments in this function.

Example

In the following example, the lrs_decimal_to_hex_string function converts an integer into a hexadecimal string. The script displays the value of the HEX string if it is not NULL.

lrs_send("socket0", "buf3", LrsLastArg);
lrs_receive("socket0", "buf4", LrsLastArg);
tmp = lrs_get_received_buffer("socket0", 29, 1, NULL);
    /* translate 4 to \x04 */
tmp2 = lrs_decimal_to_hex_string("socket0",tmp,1);
if (NULL != tmp2 && lrs_get_user_buffer_size("socket0") == 4 )
{
    lr_output_message("tmp2=%s",tmp2);
}
lrs_send("socket0", "buf5", LrsLastArg);
lrs_receive("socket0", "buf6", LrsLastArg);
