The key points for this example include the following:
setprojent() rewinds the project database to start at the beginning.
getprojent() is called with a conservative maximum buffer size that is defined in project.h.
endprojent() closes the project database and frees resources.
#include <project.h> struct project projent; char buffer[PROJECT_BUFSZ]; /* Use safe buffer size from project.h */ ... struct project *pp; setprojent(); /* Rewind the project database to start at the beginning */ while (1) { pp = getprojent(&projent, buffer, PROJECT_BUFSZ); if (pp == NULL) break; printf("%s:%d:%s\n", pp->pj_name, pp->pj_projid, pp->pj_comment); ... }; endprojent(); /* Close the database and free project resources */
The following example calls getprojbyid() to get a project database entry that matches the caller's project ID. The example then prints the project name and the project ID.
#include <project.h> struct project *pj; char buffer[PROJECT_BUFSZ]; /* Use safe buffer size from project.h */ main() { projid_t pjid; pjid = getprojid(); pj = getprojbyid(pjid, &projent, buffer, PROJECT_BUFSZ); if (pj == NULL) { /* fail; */ } printf("My project (name, id) is (%s, %d)\n", pp->pj_name, pp->pj_projid); }
