CPXXparamsetreadcopy and CPXparamsetreadcopy

The routine CPXXparamsetreadcopy/CPXparamsetreadcopy reads parameter names and settings from the file specified by filename_str and copies them into the parameter set.

int CPXXparamsetreadcopy( CPXENVptr env, CPXPARAMSETptr ps, char const * filename_str)

int CPXparamsetreadcopy( CPXENVptr env, CPXPARAMSETptr ps, char const * filename_str)

Description

The routine CPXXparamsetreadcopy/CPXparamsetreadcopy reads parameter names and settings from the file specified by filename_str and copies them into the parameter set. Note that the content of the parameter set is not cleared out before the parameters in the file are copied into the parameter set. The parameters are read from the file one by one and are added to the parameter set, or, if the parameter was already present in the set, then its value is updated.

This routine reads and copies files in the PRM format, as created by CPXXwriteparam/CPXwriteparam. The PRM format is documented in the CPLEX File Formats Reference Manual .

Arguments

env: A pointer to the CPLEX environment as returned by CPXXopenCPLEX/CPXopenCPLEX.
ps: A pointer to the CPLEX parameter set as returned by CPXXparamsetcreate/CPXparamsetcreate using env as the environment.
filename_str: Name of the file to read and copy into the parameter set.

Return

The routine returns 0 (zero) if successful and nonzero if an error occurs.

Example


        status = CPXparamsetreadcopy (env, ps, "myparams.prm");
