C Programming

The declarations in <setjmp.h> provide a way to avoid the normal function call and return sequence, typically to permit an immediate return from a deeply nested function call. (more…)

The header <signal.h> provides facilities for handling exceptional conditions that arise during execution, such as an interrupt signal from an external source or an error in execution. (more…)

The header <time.h> declares types and functions for manipulating date and time. Some functions process local time, which may differ from calendar time, for example because of time zone. clock_t and time_t are arithmetic types representing times, and struct tm holds the components of a calendar time: (more…)

The header <limits.h> defines constants for the sizes of integral types. The values below are acceptable minimum magnitudes; larger values may be used. (more…)
