XPRS_nml_getnames
The XPRS_nml_* functions provide a simple, generic interface to lists of names, which may be names of rows/columns on a problem or may be a list of arbitrary names provided by the user. The XPRS_nml_getnames function returns some of the names held in the name list. The names shall be returned in a character buffer, and with each name being separated by a NULL character.
int XPRS_CC XPRS_nml_getnames(XPRSnamelist nml, int pad, char buffer[], int maxbytes, int* p_nbytes, int first, int last);
|
nml
|
The namelist object.
|
|
pad
|
The minimum length of each name. If
>0 then names shorter than
pad will be concatenated with whitespace to make them this length.
|
|
buffer
|
Buffer of length
maxbytes into which the names shall be returned.
|
|
maxbytes
|
The maximum number of bytes that may be written to the character buffer
buffer.
|
|
p_nbytes
|
A pointer to a variable into which will be written the number of bytes required to contain the names. May be NULL if not required.
|
|
first
|
The index of the first name in the namelist to return. Note name list indexes always start from 0.
|
|
last
|
The index of the last name in the namelist to return.
