Function Documentation

void BSWP_swap16_lclXbigN ( unsigned short int *  dst,
const unsigned short int *  src,
int  cnt 
)

Byte swaps 16 bit words; local representation <=> big.

Parameters:
dst The destination array to receive the swapped words
src The source array of 16 bit words to swap
cnt The number of 16 bit words to swap
This routine transforms the source array of 16 bit integer to/from local/big endian representation from to/big endian/local representation. If the local representation is big endian, then this operation is a copy. If the local representation is big endian and the source and destination addresses are identical, then this operation is a NOOP.

Warning:
This function name is being deprecated. The new name is BSWP_swap16bN().

void BSWP_swap16_lclXlittleN ( unsigned short int *  dst,
const unsigned short int *  src,
int  cnt 
)

Byte swaps 16 bit words; local representation <=> little.

Parameters:
src The source array of 16 bit words to swap
dst The destination array to receive the swapped words
cnt The number of 16 bit words to swap
This routine transforms the source array of 16 bit integer to/from local/little endian representation from/to little endian/local representation. If the local representation is little endian, then this operation is a copy. If the local representation is little endian and the source and destination addresses are identical, then this operation is a NOOP.

Warning:
This function name is being deprecated. The new name is BSWP_swap16lN().

void BSWP_swap16bN ( unsigned short int *  dst,

Parameters:
dst The destination array to receive the swapped words
src The source array of 16 bit words to swap
cnt The number of 16 bit words to swap
This routine transforms the source array of 16 bit integer to/from local/big endian representation from to/big endian/local representation. If the local representation is big endian, then this operation is a copy. If the local representation is big endian and the source and destination addresses are identical, then this operation is a NOOP.
