Function Documentation

void* te_mem_alloc ( uint32_t  size)

Allocates memory of specified size.

Parameters
[in]sizeSize in bytes of desired memory.
Returns
A non-NULL pointer to the requested memory or NULL if the request to allocate memory failed.
void* te_mem_calloc ( uint32_t  size)

Allocates and clears memory of specified size.

Parameters
[in]sizeSize in bytes of desired memory.
Returns
A non-NULL pointer to the requested memory or NULL if the request to allocate and clear memory failed.
int te_mem_compare ( const void *  buffer1,
const void *  buffer2,
uint32_t  size 
)

Compares two ranges of memory for equality.

Parameters
[in]buffer1A pointer to first memory range to compare.
[in]buffer2A pointer to second memory range to compare.
[in]sizeNumber of bytes to compare.
Returns
An integer where:
  • 0 indicates the contents of the first memory range match match the contents of the second memory range.
  • < 0 indicates the contents of the first memory range are less than the contents of the second memory range.
  • > 0 indicates the contents of the first memory range are greater than the contents of the second memory range.
void te_mem_fill ( void *  buffer,
uint32_t  value,
uint32_t  size 
)

Fills specified memory range with specified value.

Parameters
[in]bufferA pointer to memory to fill.
[in]valueValue to use for fill operation.
[in]sizeNumber of bytes to fill.
void te_mem_free ( void *  buffer)

Frees the specified memory.

Parameters
[in]bufferA pointer to memory to free.
void te_mem_move ( void *  dest,
const void *  src,
uint32_t  size 
)

Moves specified number of bytes from a source memory range to a destination memory range.

Note
The two memory ranges may overlap.
Parameters
[out]destA pointer to destination buffer for move operation.
[in]srcA pointer to source buffer for move operation.
[in]sizeNumber of bytes to move.
void* te_mem_realloc ( void *  buffer,
uint32_t  size 
)

Changes size of memory by specified amount.

Parameters
[in]bufferPointer to memory block to resize.
[in]sizeNew size in bytes of memory block.
Returns
A non-NULL pointer to the newly resized memory or NULL if the request to resize failed.
