This lecture note provides a summary of the standard C library.

External identifiers that begin with underscores are reserved for use by the library.

Standard headers covered here are:

<errno.h>	error codes reported by library functions
<assert.h>	diagnostics
<stdarg.h>	variable argument lists
<stdio.h>	input and output
<ctype.h>	character class tests
<string.h>	string functions
<stdlib.h>	utility functions
<math.h>	mathematical functions
<time.h>	time and date functions
<setjmp.h>	non-local jumps
<signal.h>	signals
<limits.h>	implementation-defined integral type limits
<float.h>	implementation-defined floating-point limits

The following standard headers are omitted here:

<stddef.h>	definitions of general use
<locale.h>	locale-specific information
<wchar.h>	wide strings and streams
<wctype.h>	wide character class tests
<iso646.h>	ISO 646 variant character sets
