Issue of the Standard # S0158

Brief

Standard refers to matherr() function that should be defined in C99, but this definition is absent in C99

Detailed Description

LSB 3.1 refers to matherr() function that should be defined in C99, but this definition is absent in C99. This function in context of C99 is only mentioned in Rationale for International Standard—Programming Languages—C (Revision 5.10, April-2003): "The C89 Committee considered the adoption of the matherr capability from UNIX System V. In this feature of that system’s math library, any error such as overflow or underflow results in a call from the library function to a user-defined exception handler named matherr. The C89 Committee rejected this approach for several reasons".
