intro(3) — Subroutines
NAME
intro − Introduction to library functions
DESCRIPTION
This section describes functions that may be found in various libraries. The library functions are those other than the functions that directly invoke Digital UNIX system primitives, described in Section 2.
Some reference pages in this section may contain suffixes to allow their files to exist with those of other reference pages having the same base name and section number. When used, suffixes are made up of one to four letters. See the man(1) reference page for more information on suffixes.
ERRORS
Functions in the math library may return conventional values when the function is undefined for the given arguments or when the value is not representable. In these cases the external variable errno is set to the value EDOM (domain error) or ERANGE (range error). For further information, see intro(2). The values of EDOM and ERANGE are defined in the include file <math.h>.
