CCS: Xbee header file (xbee.h) for MSP430f5529

Actually I solved this issue. Have any changes or suggestion in this code tell me please... codes are below

unsigned char gbee_api(volatile char *ptr)
{
gbee_format format;
unsigned int m=0;
unsigned char i=0;
unsigned char j=0;
//13unsigned char l=0;
unsigned char z=0;
unsigned int length =0;
length =0x0E + t_l;

format.delimiter = 0x7e;
api_frame[z] = format.delimiter; // Start byte for the format (delimiter)
z++;
format.length[0] = length & 0xFF00;
api_frame[z] = format.length[0]; // MSB byte of the length(length of the format data
z++;

format.length[1] = length & 0x00FF;
api_frame[z] = format.length[1]; // LSB byte of the length
z++;

format.frame_type = 0x10;
api_frame[z] = format.frame_type; // type of the frame
z++;

format.frame_id = 0x01;
api_frame[z] = format.frame_id; // ID for the frame
z++;

format.dest_addr64[0]= (mac_address >> (8*7)) & 0xff; // mac address of the destination 64 bit
format.dest_addr64[1] = (mac_address >> (8*6)) & 0xff;
format.dest_addr64[2] = (mac_address >> (8*5)) & 0xff;
format.dest_addr64[3] = (mac_address >> (8*4)) & 0xff;
format.dest_addr64[4] = (mac_address >> (8*3)) & 0xff;
format.dest_addr64[5] = (mac_address >> (8*2)) & 0xff;
format.dest_addr64[6] = (mac_address >> (8*1)) & 0xff;
format.dest_addr64[7] = (mac_address >> (8*0)) & 0xff;
for( i=0; i<8;i++)
{
m += format.dest_addr64[i];
api_frame[z] = format.dest_addr64[i]; // TX -> data
z++;

}
format.dest_addr16[0] = 0xFF; // destination address 16 bit
format.dest_addr16[1] = 0xFE;
for(j=0; j<2;j++)
{
m +=format.dest_addr16[j];
api_frame[z] = format.dest_addr16[j]; // TX -> data
z++;

}
format.brod_rad = 0x00; //
api_frame[z] = format.brod_rad; // TX -> data
z++;

format.option = 0x00;
api_frame[z] =format.option; // TX -> data
z++;

//strcpy(*j->rf_data, ptr);
volatile unsigned int k;
for (k=0; k<=(t_l-1); k++)
{
format.rf_data[k] = ptr[k];
m += format.rf_data[k];
api_frame[z] = format.rf_data[k]; // TX -> data
z++;

// format.length++;
}
//format.rf_data[t_l]='\0';

m=m+format.frame_id + format.frame_type + format.brod_rad + format.option;

m = 0xFF & m;
format.cheksum = 0xFF - m;
api_frame[z] = format.cheksum; // TX -> data
z++;
for(i=0;i<z;i++)
{
char data;
data=api_frame[i];
while (!(UCA0IFG&UCTXIFG));
UCA0TXBUF = data; // TX -> data
}

return 0;
