AR Osal Memory Op - Qualcomm Dragonwing Documentation

Header: ar_osal/api/ar_osal_mem_op.h

Functions

`ar_mem_cpy`

ar_mem_cpy copies bytes between buffers.

int32_t ar_mem_cpy(void *dest, size_t dest_size, const void *src, size_t size)

Parameters

dest: destinatiopn buffer to copy data.

size_t

destination buffer size.

const void *

source buffer pointer to copy data from.

size_t

bytes to copy from source buffer.

Returns 0 Success Nonzero Failure

`ar_mem_move`

ar_mem_move copies bytes from source area to destination area.

int32_t ar_mem_move(void *dest, size_t dest_size, const void *src, size_t size)

Parameters

dest: destinatiopn buffer to copy data.

size_t

destination buffer size.

const void *

source buffer pointer to copy data from.

size_t

bytes to copy from source buffer.

Returns 0 Success Nonzero Failure note: If some regions of the source area and the destination overlap, ar_mem_move ensures that the original source bytes in the overlapping region are copied before being overwritten.

`ar_mem_set`

ar_mem_set set buffer to specified value.

int32_t ar_mem_set(void *dest, int32_t c, size_t size)

Parameters

dest: destinatiopn buffer to set the specified value.

int32_t

specified value to set, of integer type.

size_t

buffer bytes to set the value, must be multiple of specified value “c” data size.

Returns 0 Success Nonzero Failure

`ar_mem_cmp`

ar_mem_cmp compare two buffers.

int32_t ar_mem_cmp(const void *buff1, const void *buff2, size_t size)

Parameters

const void *

first buffer.

const void *

second buffer.

size_t

bytes to compare.

Returns 0 buff1 < buff2 0 buff1 == buff2 0 buff1 > buff2
