String

Name	Description
bzero	Erases the data in the n bytes of the memory, by write zeros('\0') to that area.
memset	Fills the data in the n bytes of the memory, by write c type to that area.
memcpy	Copies n bytes of the memory from source to dest
memccpy	Copies n bytes of the memory from source to dest, stops if the c type is found
memmove	Copies n bytes of the memory from source to dest, the copy is done in reverse order to avoid overlapping
memcmp	Compares n bytes of the memory areas in s1 and s2
memchr	Scans n bytes of the memory for the first instance of c type. Returns a pointer to the matching byte or NULL if c is not found.
memdel	Free the given memory and then puts the pointer to NULL
---- --- -- -
strcpy	Copies the string from source to dest
strcat	Appends the string source to the dest string
strncpy	Copies n bytes of the string from source to dest
strncat	Appends n bytes of the source string to the dest string
strlcpy	Copies size -1(reserved to NULL). Return the total length of the string thats tried to create(source).
strlcat	Appends the string source to the dest string where size -1 is the total size of string created. Returns the total length of the string thats was tried created, dest length + source length or size + source length if size is fewer than dest length.
strcmp	Compares the two given strings s1 and s2.
strncmp	Compares n bytes of the string areas in s1 and s2.
---- --- -- -
strlen	Returns the length of the string
strnlen	Returns the length of the string until n or NULL type is found
strclen	Returns the length of the string until first instance of c type or NULL type.
strslen	Returns the length of the string until first instance of the substr string.
---- --- -- -
strchr	Scans the string for the first instance of the c type. Returns a pointer to the matching byte or NULL if c is not found.
strrchr	Scans the string for the first instance of the c type from the last byte('\0') to the first. Returns a pointer to the matching byte or NULL if the byte is not found.
strstr	Scans the string for the first instance of the substr string. Returns a pointer to the first character of the matching strings.
strnstr	Scans n bytes of the string for the first instance of the substr string. Returns a pointer to the frist character of the matching strings.
---- --- -- -
calloc	Allocates size bytes and sets the allocate memory with zeros('\0'). Returns a pointer to the first byte of the allocated memory
strdup	Allocates and copies the given string to the allocated string. Returns a pointer to the new string.
substr	Allocates and copies a substring terminated in NULL of the given string from start until len
strjoin	Allocates s1 len + s2 len and copies the **s1 to the allocated string and then appends s2 to it. Returns a pointer to the start of the new string.
strtrim	Allocates and copies the given string without the set in the start and the end of the new string.
split	Allocates a array of strings all terminated by '\0' including the array itself (NULL)obtained by spliting s using the character c as a delimiter.
strmapi	Applies the function ’f’ to each character of the string ’s’ to create a new string resulting from successive applications of ’f’.

putnbr	Output a integer value on the screen
---- --- -- -
putchar_fd	Output a character on a given filedescriptor fd
putstr_fd	Output a string on a given filedescriptor fd
putendl_fd	Output a string with a linebreak in the end on a given filedescriptor fd
putnbr_fd	Output a integer value on a given filedescriptor fd
