◆ __reentrant
file stdlib.h 'Standard library' functions, for whatever that means.
◆ exit()
Causes normal program termination and the value of status is returned to the parent. All open streams are flushed and closed.
◆ abs()
Returns the absolute value of int i
- Parameters
-
i | Int to obtain absolute value of |
If i is negative, returns -i; else returns i.
◆ labs()
Returns the absolute value of long int num
- Parameters
-
num | Long integer to obtain absolute value of |
◆ atoi()
int atoi |
( |
const char * |
s | ) |
|
Converts an ASCII string to an int
- Parameters
-
s | String to convert to an int |
The string may be of the format
i.e. any number of spaces, an optional + or -, then an arbitrary number of digits.
The result is undefined if the number doesnt fit in an int.
Returns: Int value of string
◆ atol()
long atol |
( |
const char * |
s | ) |
|
Converts an ASCII string to a long.
- Parameters
-
s | String to convert to an long int |

- atoi()
Returns: Long int value of string
◆ itoa()
char* itoa |
( |
int |
n, |

) |
| |
Converts an int into a base 10 ASCII string.
- Parameters
-

s | String to store the converted number |
Returns: Pointer to converted string
◆ utoa()
char* utoa |
( |
unsigned int |
n, |
|
|
char * |
s |
|
) |
| |
Converts an unsigned int into a base 10 ASCII string.
- Parameters

search a sorted array of nmemb items
- Parameters
-
key | Pointer to object that is the key for the search |
base | Pointer to first object in the array to search |
nmemb | Number of elements in the array |
size | Size in bytes of each element in the array |
compar | Function used to compare two elements of the array |
Returns: Pointer to array entry that matches the search key. If key is not found, NULL is returned.
