read_scf, fread_scf, read_scf_header — Read SCF files
Scf *read_scf( char *fn);
Scf *fread_scf( FILE *fp);
int read_scf_header( FILE *fp, Header *h);
These functions read SCF format trace files. All the functions accepting a FILE * as an argument assume that the file pointer is at the correct offset within the file.
read_scf() reads an entire SCF file into the Scf structure (see the scf(4) manual page for the details of this structure). The data is read from the specified file name.
fread_scf() reads an entire SCF file into the Scf structure (see the scf(4) manual page for the details of this structure). The data is read from the specified file pointer, which is neither closed or rewound after the operation.
read_scf_header() reads the Header structure from the specified file pointer.
On successful completion, the read_scf() and fread_scf() functions return a pointer to a Scf structure. Othewise these functions return a null pointer.
On successful completion, the read_scf_header() function returns 0. Otherwise the function returns -1.
fread_scf(3) and read_scf_header(3) are aliases of read_scf(3).
