Pass address of user-supplied print routine.

Format

CXML_ITSOL_SET_PRINT_ROUTINE (user_print_routine, context, iparam)

Arguments

user_print_routine

procedure
User-supplied print routine that iterative solvers call to print messages.

context

integer*4
Integer array of length determined by the user. This argument is passed by the user to retain information for later use in USER_PRINT_ROUTINE.

iparam

integer*4
On entry, a one-dimensional array of length at least 50. The variables in the IPARAM array are assigned the values listed in Table 10-4 of the CXML Reference Guide. Of the first 50 values, the 30th - 50th elements in IPARAM are reserved for the use of CXML.

Description

CXML_ITSOL_SET_PRINT_ROUTINE passes the address of the user-supplied USER_PRINT_ROUTINE to the iterative solvers, along with context and IPARAM array.

For further information and examples about how to use this routine, refer to the "Using Iterative Solvers for Sparse Linear Systems" chapter of the CXML Reference Guide.
