(g) General functions (stdlib.h)(Continued)
Function Page Description
long labs (long i); Returns the absolute value of i; expands inline
unless
− x0 is used
7-21
ldiv_t ldiv (register long numer,
register long denom);
Divides numer by denom 7-30
int ltoa (long val, char *buffer); Converts val to the equivalent string 7-37
void *malloc (size_t size); Allocates memory for an object of size bytes 7-38
void minit (void); Resets all the memory previously allocated by
malloc, calloc, or realloc 7-40
void qsort (void *base, size_t nmemb,
size_t size, int (*compar) ());
Sorts an array of nmemb members; base points to
the first member of the unsorted array, and size
specifies the size of each member 7-43
int rand (void); Returns a sequence of pseudorandom integers in
the range 0 to RAND_MAX 7-44
void *realloc (void *packet, size_t size); Changes the size of an allocated memory space 7-44
void srand (unsigned int seed); Resets the random number generator 7-44
double strtod (const char *st, char **endptr); Converts a string to a floating-point value 7-56
long strtol (const char *st, char **endptr, int base); Converts a string to a long integer 7-56
unsigned long strtoul (const char *st,
char **endptr , int base) ;
Converts a string to an unsigned long integer 7-56
(h) String functions ( string.h )
Function Description Page
void * memchr (const void *cs, int c, size_t n); Finds the first occurrence of c in the first n charac-
ters of cs; expands inline if
− x is used
7-38
int memcmp (const void *cs, const void *ct,
size_t n);
Compares the first n characters of cs to ct;
expands inline if
− x is used
7-39
void *memcpy (void *s1, const void *s2,
register size_t n);
Copies n characters from s1 to s2 7-39
void * memmove (void *s1, const void *s2,
size_t n);
Moves n characters from s1 to s2 7-39
void * memset (void *mem, register int ch,
register size_t length);
Copies the value of ch into the first length charac-
ters of mem; expands inline if
− x is used
7-40
char * strcat (char *string1, const char *string2); Appends string2 to the end of string1 7-47
