Function family overview

This section lists C runtime library routines by function family.

CRT library routine families

_exec, _wexec
Functions to load and execute a new process.

Filename search functions
Functions to search for specified file names, and to close searches.

Format specification syntax for printf and wprintf
Describes the format string and arguments for printf and wprintf.

Format specification field characters: scanf and wscanf
Describes the format specification fields for parsing an input stream for the entire scanf family of functions.

is, isw functions
Functions for testing characters for things like whether they're uppercase, ASCII, numeric, punctuation, and so on.

_ismbb functions
Functions for testing an integer value for whether it represents an alpha character, blank character, a print character, and so on.

_ismbc functions
Functions for testing a multibyte character for whether it represents an alpha character, blank character, a print character, and so on.

operator delete (CRT)
Beginning in Visual Studio 2013, the Universal C Runtime (UCRT) no longer supports the C++-specific operator delete function. It's now part of the C++ Standard Library.

operator new (CRT)
Beginning in Visual Studio 2013, the Universal C Runtime (UCRT) no longer supports the C++-specific operator new function. It's now part of the C++ Standard Library.

printf positional parameter functions
Positional parameters specify by number the argument to substitute into a field in a format string.

scanf type field characters
The type character determines whether the associated argument is interpreted as a character, string, or number for any of the scanf family of functions, including the secure versions, such as scanf_s.

scanf width specification
The width field is a positive decimal integer that controls the maximum number of characters to be read for that field. Applies to any of the scanf family of functions, including the secure versions, such as scanf_s.

_spawn, _wspawn functions
Functions to create and execute a new process.

strcoll functions
The strcoll and wcscoll functions compare two strings according to the LC_COLLATE category setting of the locale code page.

String to numeric value functions
The strtod family of functions convert a null-terminated string to a numeric value.

vprintf functions
The vprintf functions take a pointer to an argument list, format it, and write the result to the specified destination. The functions differ in several ways: the parameter validation performed; whether they take wide or single-byte character strings; the output destination; and support for specifying the order in which parameters are used in the format string.
