Functions

Character classification routines
These functions perform character classification. They return true or false status depending whether the character passed to the function falls into the function's classification (i.e. isdigit() returns true if its argument is any value '0' though '9', inclusive). If the input is not an unsigned char value, all of this function return false.

int isalnum (int __c) __ATTR_CONST__
int isalpha (int __c) __ATTR_CONST__
int isascii (int __c) __ATTR_CONST__
int isblank (int __c) __ATTR_CONST__
int iscntrl (int __c) __ATTR_CONST__
int isdigit (int __c) __ATTR_CONST__
int isgraph (int __c) __ATTR_CONST__
int islower (int __c) __ATTR_CONST__
int isprint (int __c) __ATTR_CONST__
int ispunct (int __c) __ATTR_CONST__
int isspace (int __c) __ATTR_CONST__
int isupper (int __c) __ATTR_CONST__
int isxdigit (int __c) __ATTR_CONST__
Character convertion routines
This realization permits all possible values of integer argument. The toascii() function clears all highest bits. The tolower() and toupper() functions return an input argument as is, if it is not an unsigned char value.

int tolower (int __c) __ATTR_CONST__
int toupper (int __c) __ATTR_CONST__
