Detailed Description

These functions perform byte swapping of 16 and 32-bit values.

The 64-bit versions of these functions are documented under 64-bit Support

Functions

	Byte swaps a 16-bit signed value.
posh_u32_t	POSH_SwapU32 (posh_u32_t v)
	Byte swaps a 32-bit unsigned value.
posh_i32_t	POSH_SwapI32 (posh_i32_t v)
	Byte swaps a 32-bit signed value.

Function Documentation

posh_i16_t POSH_SwapI16 (  posh_i16_t  v  )

Byte swaps a 16-bit signed value. Parameters: v  [in] signed 16-bit input value to swap Returns: a byte swapped version of v Remarks: This just calls back to the unsigned version, since byte swapping is independent of sign. However, we still provide this function to avoid signed/unsigned mismatch compiler warnings. Definition at line 310 of file posh.c. References posh_i16_t, and POSH_SwapU16().

posh_i32_t POSH_SwapI32 (  posh_i32_t  v  )

Byte swaps a 32-bit signed value. Parameters: v  [in] signed 32-bit input value to swap Returns: a byte swapped version of v Remarks: This just calls back to the unsigned version, since byte swapping is independent of sign. However, we still provide this function to avoid signed/unsigned mismatch compiler warnings. Definition at line 346 of file posh.c. References posh_i32_t, POSH_SwapU32(), and posh_u32_t.

posh_u16_t POSH_SwapU16 (  posh_u16_t  v  )

Byte swaps a 16-bit unsigned value. Parameters: v  [in] unsigned 16-bit input value to swap Returns: a byte swapped version of v Definition at line 289 of file posh.c. References posh_u16_t. Referenced by POSH_SwapI16().

posh_u32_t POSH_SwapU32 (  posh_u32_t  v  )

Byte swaps a 32-bit unsigned value. Parameters: v  [in] unsigned 32-bit input value to swap Returns: a byte swapped version of v Definition at line 323 of file posh.c. References posh_u32_t. Referenced by POSH_FloatFromBigBits(), POSH_FloatFromLittleBits(), and POSH_SwapI32().
