XPRSnlpgetformulastr

Purpose
Retrieve a single matrix formula in a character string.
Synopsis
int XPRS_CC XPRSnlpgetformulastr(XPRSprob prob, int row, char *formula, int maxbytes, int *p_nbytes);
Arguments
prob 
The current SLP problem.
row 
Integer holding the row index for the formula.
formula 
Character buffer in which the formula will be placed in the same format as used for input from a file. The formula will be null terminated. This argument may be NULL if maxbytes is zero.
maxbytes 
Length of the formula buffer.
p_nbytes 
Will be set to the length of the formula, not including the null terminator.
Example
The following retrieves a formula in text form: 
char *buffer;
int len;

XPRSnlpgetformulastr(prob, 2, NULL, 0, &len);
buffer = malloc(len + 1);
XPRSnlpgetformulastr(prob, 2, buffer, len + 1, NULL);
Further information

If the length of the formula would exceed maxbytes-1, the formula is truncated to the last token that will fit, and the (partial) formula is terminated with a null character.
