宏定义说明
◆ Calloc
| #define Calloc | ( | req_count, | |
| req_size | |||
| ) | tal_calloc(req_count, req_size) |
malloc consecutive memory, the size is reqCount*reqSize
- 参数
-
[in] reqCount the required memory count [in] reqSize the required memory szie
- 返回
- NULL on failed, others on the address of the memory
◆ Free
| #define Free | ( | ptr | ) | tal_free(ptr) |
free memory
- 参数
-
[in] pReqMem the memory address which got from Malloc or Calloc function
- 返回
- VOID
◆ Malloc
| #define Malloc | ( | req_size | ) | tal_malloc(req_size) |
malloc memory
- 参数
-
[in] reqSize the required memory size
- 返回
- NULL on failed, others on the address of the memory
函数说明
◆ tal_calloc()
| VOID_T * tal_calloc | ( | SIZE_T | nitems, |
| SIZE_T | size | ||
| ) |
Allocate and clear the memory
- 参数
-
[in] nitems the numbers of memory block [in] size the size of the memory block
- 返回
- the memory address calloced
◆ tal_free()
| VOID_T tal_free | ( | VOID_T * | ptr | ) |
Free memory of system
- 参数
-
[in] ptr memory point
- 注解
- This API is used to free memory of system.
- 返回
- VOID_T
◆ tal_malloc()
| VOID_T * tal_malloc | ( | SIZE_T | size | ) |
Alloc memory of system
- 参数
-
[in] size memory size
- 注解
- This API is used to alloc memory of system.
- 返回
- the memory address malloced
◆ tal_realloc()
| VOID_T * tal_realloc | ( | VOID_T * | ptr, |
| SIZE_T | size | ||
| ) |
Re-allocate the memory
- 参数
-
[in] nitems source memory address [in] size the size after re-allocate
- 返回
- VOID_T
◆ tal_system_memcmp()
| INT_T tal_system_memcmp | ( | CONST VOID_T * | str1, |
| CONST VOID_T * | str2, | ||
| SIZE_T | n | ||
| ) |
Compare the first n bytes of store str1 and store str2
- 参数
-
[in] str1 point to string1 [in] str2 point to string2 [in] n first n bytes
- 注解
- This API is used to compare two strings
- 返回
- value < 0: str1 is less than str2; value > 0: str1 is greater than str2; value = 0: str1 is equal to str2;
◆ tal_system_memcpy()
| VOID_T * tal_system_memcpy | ( | VOID_T * | dst, |
| CONST VOID_T * | src, | ||
| SIZE_T | n | ||
| ) |
Alloc memory of system
- 参数
-
[in] size memory size
- 注解
- This API is used to alloc memory of system.
- 返回
- the memory address malloced
◆ tal_system_memset()
| VOID_T * tal_system_memset | ( | VOID_T * | src, |
| INT_T | ch, | ||
| SIZE_T | n | ||
| ) |
set memory
- 参数
-
[in] size memory size
- 注解
- This API is used to alloc memory of system.
- 返回
- the memory address malloced
