In glpk 4.10 there are four api routines (not documented yet):

void lpx_create_index(LPX *lp) creates an index to find rows and
columns by symbolic names for logarithmic time. This routine can be
called at any time before using routines lpx_find_row and
lpx_find_col.

int lpx_find_row(LPX *lp, char *name) returns the ordinal number
of a row which is assigned a specified symbolic name (through the
routine lpx_set_row_name). If no such row exists, 0 is returned.

int lpx_find_col(LPX *lp, char *name) does the same for a column.

lpx_delete_index(LPX *lp) destroys the index. It can be called at
any time, if necessary.
