void *memchr(const void *str, int c, size_t n)
Searches for the first occurrence of the character c (an unsigned char) in the first n bytes of the string pointed to, by the argument str.
int memcmp(const void *str1, const void *str2, size_t n)
Compares the first n bytes of str1 and str2.
void *memcpy(void *dest, const void *src, size_t n)
Copies n characters from src to dest.
void *memmove(void *dest, const void *src, size_t n)
Another function to copy n characters from str2 to str1.
void *memset(void *str, int c, size_t n)
Copies the character c (an unsigned char) to the first n characters of the string pointed to, by the argument str.
char *strcat(char *dest, const char *src)
Appends the string pointed to, by src to the end of the string pointed to by dest.
char *strncat(char *dest, const char *src, size_t n)
Appends the string pointed to, by src to the end of the string pointed to, by dest up to n characters long.
char *strchr(const char *str, int c)
Searches for the first occurrence of the character c (an unsigned char) in the string pointed to, by the argument str.
int strcmp(const char *str1, const char *str2)
Compares the string pointed to, by str1 to the string pointed to by str2.
int strncmp(const char *str1, const char *str2, size_t n)
Compares at most the first n bytes of str1 and str2.
int strcoll(const char *str1, const char *str2)
Compares string str1 to str2. The result is dependent on the LC_COLLATE setting of the location.
char *strcpy(char *dest, const char *src)
Copies the string pointed to, by src to dest.
char *strncpy(char *dest, const char *src, size_t n)
Copies up to n characters from the string pointed to, by src to dest.
size_t strcspn(const char *str1, const char *str2)
Calculates the length of the initial segment of str1 which consists entirely of characters not in str2.
char *strerror(int errnum)
Searches an internal array for the error number errnum and returns a pointer to an error message string.
size_t strlen(const char *str)
Computes the length of the string str up to but not including the terminating null character.
char *strpbrk(const char *str1, const char *str2)
Finds the first character in the string str1 that matches any character specified in str2.
char *strrchr(const char *str, int c)
Searches for the last occurrence of the character c (an unsigned char) in the string pointed to by the argument str.
size_t strspn(const char *str1, const char *str2)
Calculates the length of the initial segment of str1 which consists entirely of characters in str2.
char *strstr(const char *haystack, const char *needle)
Finds the first occurrence of the entire string needle (not including the terminating null character) which appears in the string haystack.
char *strtok(char *str, const char *delim)
Breaks string str into a series of tokens separated by delim.
