flexiblas_list(3) The FlexiBLAS Library flexiblas_list(3) NAME flexiblas_list - list available backends. SYNOPSIS #include <flexiblas/flexiblas_api.h> int flexiblas_list(char *name, size_t len, int pos Link with -lflexiblas. DESCRIPTION flexiblas_list returns information about the available FlexiBLAS backends. If the buffer name is set to NULL the function returns the number of avail- able backends in the FlexiBLAS configuration files. Otherwise the name pa- rameter needs to be a character buffer of size len and the pos arguments specifies the number of the entry to return. The name of the backend is then copy to the buffer name with a length of at most len and the real length of the backend name is returned. The name is copied into the buffer using strncpy with a maximum length of len. The pos parameter is valid in a range from 0..B-1, where B is the number of backends returned by a first call to flexiblas_list with a NULL buffer. If the buffer is not large enough, i.e. the return value equals len-1, the returned named can not be used in other FlexiBLAS API calls like flexi- blas_load_backend. RETURN VALUE On success, it returns the number of entries in the FlexiBLAS configuration if name==NULL or the length of the returned name using strlen. In case of an error, like an out of range index pos, a negative number is returned. ERRORS All negative return values are errors. EXAMPLE The following example show how to list all available backends.
