Defined in header <math.h> float truncf( float arg ); (1) (since C99) double trunc( double arg ); (2) (since C99) long double truncl( long double arg ); (3) (since C99) Defined in header <tgmath.h> #define trunc( arg ) (4) (since C99) 1-3) Computes the nearest integer not greater in magnitude than arg. 4) Type-generic macro: If arg has type long double, truncl is called. Otherwise, if arg has integer type or the type double, trun

Defined in header <ctype.h> int isgraph( int ch ); Checks if the given character has a graphical representation, i.e. it is either a number (0123456789), an uppercase letter (ABCDEFGHIJKLMNOPQRSTUVWXYZ), a lowercase letter (abcdefghijklmnopqrstuvwxyz), or a punctuation character(!"#$%&'()*+,-./:;<=>?@[\]^_`{|}~), or any graphical character specific to the current C locale. The behavior is undefined if the value of ch is not representable as unsigned char and is no

Defined in header <wctype.h> int iswblank( wint_t ch ); (since C99) Checks if the given wide character is classified as blank character (that is, a whitespace character used to separate words in a sentence) by the current C locale. In the default C locale, only space (0x20) and horizontal tab (0x09) are blank characters. Parameters ch - wide character Return value Non-zero value if the wide character is a blank character, zero otherwise. Example #include

Defined in header <wctype.h> int iswdigit( wint_t ch ); (since C95) Checks if the given wide character corresponds (if narrowed) to one of the ten decimal digit characters 0123456789. Parameters ch - wide character Return value Non-zero value if the wide character is an numeric character, zero otherwise. Notes iswdigit and iswxdigit are the only standard wide character classification functions that are not affected by the currently installed C locale. Exa

Transfers control unconditionally to the desired location. Used when it is otherwise impossible to transfer control to the desired location using conventional constructs. Syntax goto label ; label : statement Explanation The goto statement causes an unconditional jump (transfer of control) to the statement prefixed by the named label (which must appear in the same function as the goto statement), except when this jump would enter the scope of a variable-length array or anoth

Defined in header <stdlib.h> void abort_handler_s( const char * restrict msg, void * restrict ptr, errno_t error ); (since C11) Writes an implementation-defined message to stderr which must include the string pointed to by msg and calls abort(). A pointer to this function can be passed to set_constraint_handler_s to establish a runtime constraints violation handler. As with all bounds-checked functions, abort_

Defined in header <math.h> #define isnan(arg) /* implementation defined */ (since C99) Determines if the given floating point number arg is a not-a-number (NaN) value. The macro returns an integral value. FLT_EVAL_METHOD is ignored: even if the argument is evaluated with more range and precision than its type, it is first converted to its semantic type, and the classification is based on that (this matters if the evaluation type supports NaNs, while the semantic type does n

Defined in header <complex.h> float complex cacosf( float complex z ); (1) (since C99) double complex cacos( double complex z ); (2) (since C99) long double complex cacosl( long double complex z ); (3) (since C99) Defined in header <tgmath.h> #define acos( z ) (4) (since C99) 1-3) Computes the complex arc cosine of z with branch cuts outside the interval [−1,+1] along the real axis. 4) Type-generic macro: If z has type long double

Defined in header <wchar.h> (1) wchar_t *wcscpy( wchar_t *dest, const wchar_t *src ); (since C95) (until C99) wchar_t *wcscpy( wchar_t *restrict dest, const wchar_t *restrict src ); (since C99) errno_t wcscpy_s( wchar_t *restrict dest, rsize_t destsz, const wchar_t *restrict src ); (2) (since C11) 1) Copies the wide string pointed to by src (including the terminating null wide character) to wide character array pointed to by dest. The behavior
