This code example uses the label_to_str() function to obtain the color name of a label. The mappings between color names and labels are defined in the label_encodings file.
#include <stdlib.h> #include <stdio.h> #include <tsol/label.h> int main() { m_label_t *plabel; char *label = NULL; char *color = NULL; plabel = m_label_alloc(MAC_LABEL); if (getplabel(plabel) == -1) { perror("getplabel"); exit(1); } if (label_to_str(plabel, &color, M_COLOR, 0) != 0) { perror("label_to_string(M_COLOR)"); exit(1); } if (label_to_str(plabel, &label, M_LABEL, DEF_NAMES) != 0) { perror("label_to_str(M_LABEL)"); exit(1); } printf("The color for the \"%s\" label is \"%s\".\n, label, color); m_label_free(plabel); return (0); }
If the label_encodings file maps the color blue to the label CONFIDENTIAL, the program prints the following:
The color for the "CONFIDENTIAL" label is "BLUE".
