NWSMPadBlankSpace

Inserts a blank space section if there is room in the buffer, or fills the unused area of a buffer with zeros.

Syntax

  #include <smsutapi.h> 
   
  void NWSMPadBlankSpace ( 
     BUFFERPTR   bufferPtr, 
     UINT32      unusedSize);

Parameters

bufferPtr: (OUT) Points to the area in the buffer to fill with blank spaces or zeros.
unusedSize: (IN) Specifies the size of the area in buffer to pad.

Remarks

If unusedSize is less than MIN_BLANK_SPACE_SECTION_SIZE, the unused area is filled with zeros. If unusedSize is larger than or equal to MIN_BLANK_SPACE_SECTION_SIZE, the Blank Space section is put into the unused area.

NWSMPadBlankSpace Example

  #define BUFFER_SIZE 2048 /* Arbitrary size. */ 
  char buf[BUFFER_SIZE]; 
  BUFFERPTR bufferPtr = buf; 
  UINT32 unusedSize = BUFFER_SIZE; 
   
  /* Put data into buffer pointed to by bufferPtr. */ 
  /* Update buffer information. */ 
  bufferPtr = bufferPtr + amount of data put into buffer; 
  unusedSize -= (bufferPtr - buf); 
   
  /* Pad unused buffer area. */ 
  NWSMPadBlankSpace(bufferPtr, unusedSize);
