#define atof (  STR   )     strtod((STR), (char **)NULL)

NAME atof - convert a string to a double. SYNOPSIS #include <stdlib.h> double atof(const char *nptr); DESCRIPTION The atof() function converts the initial portion of the string pointed to by nptr to double. The behaviour is the same as strtod(nptr, (char **)NULL); except that atof() does not detect errors. RETURN VALUE The converted value. IMPLEMENTATION for APEnext: for simplicity, it's the same as strtod(). Definition at line 95 of file stdlib.h.

#define atoi (  nptr   )     strtol(nptr, (char **)NULL, 10)

NAME atoi, atol, atoll, atoq - convert a string to an integer. SYNOPSIS #include <stdlib.h> int atoi(const char *nptr); long atol(const char *nptr); long long atoll(const char *nptr); long long atoq(const char *nptr); DESCRIPTION The atoi() function converts the initial portion of the string pointed to by nptr to int. The behaviour is the same as strtol(nptr, (char **)NULL, 10); except that atoi() does not detect errors. The atol() and atoll() functions behave the same as atoi(), except that they convert the initial portion of the string to their return type of long or long long. atoq() is an obsolete name for atoll(). RETURN VALUE The converted value. IMPLEMENTATION for APEnext: for simplicity, all are mapped to the corresponding strto*() functions. Definition at line 132 of file stdlib.h.

Function Documentation

void abort (  void   )  [inline]

Definition at line 244 of file stdlib.h.

int abs (  int  i  )  [inline]

NAME abs, labs, llabs, imaxabs - compute the absolute value of an integer. SYNOPSIS #include <stdlib.h> int abs(int j); long int labs(long int j); long long int llabs(long long int j); #include <inttypes.h> intmax_t imaxabs(intmax_t j); DESCRIPTION The abs() function computes the absolute value of the integer argument j. The labs(), llabs() and imaxabs() functions compute the absolute value of the argument j of the appropriate integer type for the function. RETURN VALUE Returns the absolute value of the integer argument, of the appropriate integer type for the function. IMPLEMENTATION for APEnext: possible (abs,labs,llabs) -------------------------------------------------------------------------- Definition at line 491 of file stdlib.h.

div_t div (  int  numer, int  denom )  [inline]

NAME div - computes the quotient and remainder of integer divi­ sion SYNOPSIS #include <stdlib.h> div_t div(int numer, int denom); DESCRIPTION The div() function computes the value numer/denom and returns the quotient and remainder in a structure named div_t that contains two integer members named quot and rem. RETURN VALUE The div_t structure. IMPLEMENTATION for APEnext: done (needs to be optimized), tested ------------------------------------------------------------------------- Definition at line 530 of file stdlib.h. References div_t::quot, and div_t::rem.

ldiv_t ldiv (  long int  numer, long int  denom )  [inline]

Definition at line 541 of file stdlib.h. References ldiv_t::quot, and ldiv_t::rem.

lldiv_t lldiv (  long long int  numer, long long int  denom )  [inline]

Definition at line 552 of file stdlib.h. References lldiv_t::quot, and lldiv_t::rem.

int system (  const char *  s  )

NAME system - execute a shell command SYNOPSIS #include <stdlib.h> int system (const char * string); DESCRIPTION system() executes a command specified in string by calling /bin/sh -c string, and returns after the command has been completed. During execution of the command, SIGCHLD will be blocked, and SIGINT and SIGQUIT will be ignored. RETURN VALUE The value returned is -1 on error (e.g. fork failed), and the return status of the command otherwise. This latter return status is in the format specified in wait(2). Thus, the exit code of the command will be WEXITSTA­ TUS(status). In case /bin/sh could not be executed, the exit status will be that of a command that does exit(127). If the value of string is NULL, system() returns nonzero if the shell is available, and zero if not. system() does not affect the wait status of any other children. IMPLEMENTATION for APEnext: implemented (needs to be tested) (system) ----------------------------------------------------------------------------
