Error: Section 12.4.3 - p. 515 - MPI_INIT argc/argv values

[wesbland]

Problem

The text about "argc and argv is optional" is incorrect - the arguments are required, but the values may be NULL. This should be compared with MPI_Init and both made consistent and correct. Specifically, this text:

In C, the passing of argc and argv is optional, as with MPI_INIT as discussed in Section 8.7. In C, null pointers may be passed in their place.

should use the same text as for MPI_INIT.

Suggested Fix

Change to "The version for ISO C accepts the argc and argv that are provided by the arguments to main or NULL."

The voters indicated that they think this is errata (and I agree):

• Editor change - 1
• Chapter committee - 2
• Errata - 4
