The following table lists and describes string and block copy intrinsics that you can use across all Intel architectures.
The string and block copy intrinsics are not implemented as intrinsics on IA-64 architecture.
| Intrinsic | Description |
|---|---|
| char *_strset(char *, _int32) | Sets all characters in a string to a fixed value. |
| int memcmp(const void *cs, const void *ct, size_t n) | Compares two regions of memory. Return <0 if cs<ct, 0 if cs=ct, or >0 if cs>ct. |
| void *memcpy(void *s, const void *ct, size_t n) | Copies from memory. Returns s. |
| void *memset(void * s, int c, size_t n) | Sets memory to a fixed value. Returns s. |
| char *strcat(char * s, const char * ct) | Appends to a string. Returns s. |
| int strcmp(const char *, const char *) | Compares two strings. Return <0 if cs<ct, 0 if cs=ct, or >0 if cs>ct. |
| char *strcpy(char * s, const char * ct) | Copies a string. Returns s. |
| size_t strlen(const char * cs) | Returns the length of string cs. |
| int strncmp(char *, char *, int) | Compare two strings, but only specified number of characters. |
| int strncpy(char *, char *, int) | Copies a string, but only specified number of characters. |
